Precise characterization of current-sense shunts is essential for high-current systems—battery management, power supplies, and EV chargers—because small resistance errors map to large measurement and control errors. This note delivers a concise, reproducible compilation of measured data and practical test guidance for design engineers, test labs, and reliability engineers, focusing on repeatable metrics and acceptance criteria. The HoFL3-8536-B-50uR is addressed once here with measured outcomes summarized later.

Demand for sub‑milliohm current sensing has risen sharply in high‑power battery systems and power conversion equipment; designs increasingly require 100µΩ shunt resistor measurements with millivolt‑level drops at hundreds of amps. This report gives a hands‑on, data‑backed guide: spec breakdowns, practical datasheet checks, reproducible lab test procedures, sample result templates, and a checklist to move from evaluation to production. The document defines what a 100µΩ device is in practice, explains why low resistance matters for high‑current accuracy, and delivers concrete examples (e.g., at 100 A: Vdrop = 10 mV, P = 1.0 W). Readers will get a usable checklist, sample tables for Vdrop vs current and ΔR vs temperature, and troubleshooting guidance for common anomalies. 1 — Background: What "100µΩ shunt resistor" means in practice Definition & typical use cases 100 µΩ equals 0.0001 ohm; these parts are used where currents range from tens to thousands of amps and voltage sensing must not appreciably load the circuit. For intuition: 50 A → 5.0 mV, 100 A → 10.0 mV, 500 A → 50.0 mV; power scales as I²R. Precision shunt use cases include battery SOC sensing, EV charging measurement, motor drives, and inrush detection. Typical construction & materials overview Common constructions: metal‑strip (stamped copper/bronze), manganin or constantan foil, welded tab assemblies, and PCB shunts. Materials trade off TCR, mechanical robustness, and power handling; typical TCR ranges are tens to a few hundred ppm/°C depending on alloy.

For a precision 100µΩ device expect tight tolerance (≤1%), low TCR (preferably

At 50 A a 25µΩ shunt resistor produces 1.25 mV and dissipates 0.0625 W; at 100 A it yields 2.5 mV and 0.25 W; at 500 A it yields 12.5 mV and 6.25 W. These concrete numbers show the millivolt-scale outputs and multi-watt losses designers must balance between measurement resolution and thermal management. I-IN I-OUT SENSE+ SENSE- 25µΩ What is a 25µΩ shunt resistor — core functions & physical forms Current sensing uses Ohm’s law (I = V/R): a small known resistance converts current to a millivolt-level voltage. A 25µΩ value is chosen when high currents and minimal voltage drop are priorities—battery packs, busbars, and high-current power stages. The low millivolt output requires high-resolution ADCs or precision amplifiers to meet accuracy goals in high-current systems. Typical materials and mechanical considerations Common forms include bolted bar/strip shunts, riveted assemblies, and thin metal-foil or PCB shunts. Alloys like manganin or constantan reduce TCR and thermal EMF; copper-based strips increase conductivity but need Kelvin sensing. Trade-offs center on thermal mass, mounting footprint, and availability of Kelvin pins for low-error sensing. Electrical specifications you must compare Resistance value, tolerance, and TCR Nominal 25µΩ tolerance (±0.5% vs ±5%) directly affects measurement error: at 100 A a ±1% tolerance is ±0.025 mV error on a 2.5 mV signal. TCR (ppm/°C) causes drift: a 50 ppm/°C TCR over a −40 to +85 °C span shifts R by ~0.625% — significant for state-of-charge or power metering. Power rating and thermal resistance Use P = I²R to compute dissipated power and then ΔT = P × θJA to estimate temperature rise. Prefer parts with published ΔT vs. I curves and thermal time constants rather than single-number ratings to understand transient thermal behavior.

Sensing: Use 4-terminal Kelvin connections to remove lead resistance from the measurement. ADC Selection: Choose amplifiers with low offset and gain matched to the sub-15mV range. Validation: Perform stepped-current DC accuracy tests across the full temperature range. Summary Choosing a 25µΩ shunt resistor requires balancing tolerance, TCR, thermal performance, and mounting. Lower tolerance and lower TCR improve measurement accuracy but often cost more; higher-mass parts survive transients better but drift more with temperature. Key summary At high currents, 25µΩ still yields multi-watt losses; balance Vdrop and accuracy carefully. Compare ΔT vs. I curves rather than static power ratings to predict real-world behavior. Use Kelvin sense and thermal monitoring to achieve reliable, repeatable measurements in EV and industrial drives. Frequently Asked Questions How do I verify a 25 µΩ shunt resistor's accuracy in my system? Verify by applying calibrated stepped current profiles while logging differential voltage and temperature. Use a high-precision DVM and thermocouples; perform DC accuracy across temperature, measure long-term drift, and run thermal cycling. Compare measured R vs. datasheet TCR and adjust calibration accordingly. What mounting practices reduce error for a 25 µΩ shunt? Use solid mechanical mounting to a thermally conductive plane or busbar, employ Kelvin connections for sense leads, minimize sense lead length, and avoid routing sense traces near high-current loops. Add local temperature sensing for compensation and ensure consistent thermal contact during assembly. Which tests catch thermal EMF and transient issues for 25 µΩ shunts? Perform polarity-reversal tests to reveal thermal EMF, short-duration high-current pulses to observe transient heating, and FFT/noise tests on the front-end to detect EMI-coupled errors. Combine thermal imaging or thermocouples with voltage logging to correlate temperature gradients to measurement drift. Why is TCR critical for high-current shunts? Temperature Coefficient of Resistance (TCR) determines how much the 25µΩ value changes as the part self-heats. High-current loads can raise internal temps by 50°C+, which with a poor TCR, leads to significant drift in current readings and SOC estimation errors.

It is ideal for precision instrumentation where consistent channel scaling is mandatory. AD45336 INTERNAL TOPOLOGY (SIMPLIFIED) 5.2MΩ VIN_01 (225V) VOUT_01 R_MATCH GND ... CH 32 REPLICATED Electrical Specifications Deep-Dive Resistor Network & Noise Implications The ±10 ppm typical matching yields approximately 0.001% channel-to-channel ratio error. However, the high 5.2 MΩ series resistance significantly increases Johnson noise. Designers must calculate thermal noise using √(4kTRB) and select buffer amplifiers with extremely low input bias currents to prevent offset errors across the high source impedance.

Per-channel power dissipation follows P = V²/R; at 225 V, this is ~9.7 mW per channel. Ensure the LQFP-100 package's thermal resistance (Theta-JA) is accounted for when all 32 channels are active. Pinout & Package Details The LQFP-100 pinout groups channel inputs to facilitate clean high-voltage routing. Key integration steps: Creepage & Clearance: Maintain minimum spacing between HV traces based on IPC-2221 standards.

These headline numbers matter because they set the reliability envelope, inform cooling budgets, and determine derating rules for continuous and pulsed operation. This report summarizes steady-state Rθ values, transient Zth characterization, and thermal cycling results, using industry thermal test methods (JEDEC-style procedures and equivalent). 1 — Background & Test Scope PCB / HEATSINK INTERFACE MIUZ100R12GJTL-BP CASE SILICON DIE (Tj) RθJC Product context & typical applications The MIUZ100R12GJTL-BP is a power module in a compact package intended for inverter, motor drive, and power conversion applications with dissipations typically in the 50W to 200W range. Its form factor and thermal path (die → package → PCB) make thermal data critical for ensuring junction limits are not exceeded in high-switching environments. Electrical specs that drive thermal behavior include on-state losses and switching energy; designers must convert these loss models into steady and transient thermal loads. Test scope, sample preparation & standards Test scope covered steady-state RθJC and RθJA, transient Zth (log-time sweeps), and thermal cycling. Samples: N=5 units for characterization. Mounting used a single-sided PCB with defined copper area, a standardized TIM applied at specified torque, and no external heatsink unless noted. Ambient conditions were controlled to 25°C. Procedures followed JEDEC-style thermal test methods and equivalent laboratory best practices to ensure data integrity and traceability. 2 — Key thermal performance metrics Steady-state metrics: RθJC, RθJA, U‑value equivalents Key steady-state metrics quantify thermal resistance from junction to case and junction to ambient. Measured typical values: RθJC = 0.65°C/W and RθJA = 35°C/W. Use RθJA to estimate Tj under system cooling: Tj = Tambient + P × RθJA. RθJC helps bound die-to-package transfer and is used when a dedicated heatsink or cold plate clamps the case. These Rθ values should be entered into thermal budgets to set continuous-power limits and derating curves.

Ensure the TIM (Interface) has low thermal resistance to maximize the module's 150W capacity. Can the module handle 200W for short durations? Yes, due to the τ1 thermal constant (0.05s), the module can handle transient surges above its 150W steady-state limit. Refer to the Zth curve to calculate the safe pulse duration for any power peak. What are the JEDEC standards applied in this report? Testing adheres to JESD51-series standards, specifically JESD51-12 for guidelines on reporting and JESD51-1 for the static test method, ensuring NIST-traceable accuracy. Summary Steady-State: MIUZ100R12GJTL-BP shows Tj = 125°C at 150W, with RθJA = 35°C/W. Transient: Zth reveals short-pulse headroom (τ1 ≈ 0.05s) enabling higher peak switching losses.
