Common Mode Chokes Procurement Notes

Verify the specific part number suffix against official Sumida documentation to confirm electrical characteristics. Ensure the through-hole package type matches the target PCB layout requirements. Confirm that the 400 mA current rating and 2.6 Ohm DC resistance meet the circuit design specifications before procurement.

Common Mode Chokes Selection Notes

Select this component when a high-inductance common mode choke is required for low-current power lines. The 52 mH value provides significant noise attenuation. Verify that the 400 mA saturation current aligns with the maximum operating current of the application to prevent performance degradation.

Common Mode Chokes Part Context

This component belongs to the LF2020BNP series of common mode chokes from Sumida. The series includes various inductance values tailored for different EMI suppression needs. The LF2020BNP-R523 specifically targets applications requiring higher inductance for effective noise filtering in power supply circuits.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the LF2020BNP series or equivalent Sumida parts with matching 52 mH inductance and 400 mA current ratings. Ensure any replacement maintains the through-hole package and similar DC resistance characteristics.
