Procurement Notes

Verify the complete ordering code including suffixes against official TDK documentation to ensure exact electrical specifications. Confirm package type and pinout compatibility during design-in. Request manufacturer datasheets for thermal derating curves and impedance characteristics. Validate compliance requirements relevant to the target application region before procurement.

Selection Notes

Select this component when high inductance values are required for low-frequency noise attenuation in single-phase AC lines. Ensure the continuous current rating meets the peak load requirements without saturation. Consider the physical dimensions and lead spacing for PCB layout constraints. Evaluate thermal performance under maximum ambient conditions to maintain reliability.

Part Context

This component belongs to the B82732 series of current-compensated chokes from EPCOS/TDK. These components utilize ferrite cores optimized for power line applications. The series offers various inductance and current ratings to suit different filtering needs across consumer, industrial, and automotive sectors.

Replacement Considerations

Consult official TDK substitution guides for verified equivalents. Cross-reference inductance, current rating, and physical dimensions carefully. Generic substitutes may not match the specific core material or frequency response characteristics.
