Procurement Notes

Verify the specific suffix N001 against the manufacturer's official datasheet to confirm exact tolerance and packaging specifications. Ensure the selected variant matches the required 1.5 mH inductance and 1.5 A current rating for the target application circuit. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by EPCOS or TDK Electronics prior to procurement.

Selection Notes

Select this component when designing circuits requiring common mode filtering for 250 V AC lines with currents up to 1.5 A. The 1.5 mH inductance value is suitable for suppressing higher frequency noise compared to lower inductance variants. Consider the radial package dimensions and operating temperature range of -40 °C to +125 °C to ensure compatibility with the mechanical constraints and thermal environment of the final assembly.

Part Context

This part is part of the B82721 series of power line chokes from EPCOS (TDK). The series offers various inductance values and current ratings tailored for different power levels. These components are widely used in passive filtering applications where compact size and reliable performance in AC mains environments are required. The B82721K0152N001 represents a specific configuration within this family optimized for 1.5 A applications.

Replacement Considerations

Consult the official EPCOS/TDK replacement guide for direct substitutes. Verify that any alternative maintains the same 1.5 mH inductance, 1.5 A current rating, and 250 V AC voltage rating. Ensure physical footprint compatibility for radial through-hole mounting.
