CFR-25JB-52-1M2 Fixed Inductors highlighting the core functional technology articles and application development cases of Fixed Inductors that are effective.

1. Inductance: The inductance value, typically measured in microhenries (µH) or millihenries (mH), indicates the inductor's ability to store energy in a magnetic field. This value is crucial for determining how the inductor will behave in a circuit, especially in filtering and energy storage applications.

2. DC Resistance (DCR): The DCR is the resistance encountered by direct current flowing through the inductor. A lower DCR is desirable as it reduces power losses and improves efficiency, particularly in power supply applications.

3. Saturation Current: This parameter defines the maximum current the inductor can handle before its inductance begins to decrease significantly. Knowing the saturation current is vital for ensuring that the inductor operates within its safe limits, preventing overheating and performance degradation.

4. Self-Resonant Frequency (SRF): The SRF is the frequency at which the inductor's reactance equals its resistance, causing it to resonate. Understanding the SRF is important for avoiding unwanted resonances in high-frequency applications, which can lead to signal distortion.

5. Temperature Coefficient: This indicates how the inductance value changes with temperature variations. A stable temperature coefficient is important for applications where the inductor may experience significant temperature fluctuations.
