Procurement Notes

Verify the specific suffix code against official EPCOS/TDK documentation to confirm electrical characteristics, as variations exist within the B82720H series. Ensure compatibility with operating temperature ranges and voltage ratings required by the target application. Cross-reference datasheet parameters such as inductance tolerance and DC resistance before integration.

Selection Notes

Select this component when designing filters for data lines requiring 28 mH inductance at currents up to 400 mA. Consider the physical footprint of 13.00 mm x 9.50 mm for PCB layout constraints. Evaluate the 1.2 Ohm DC resistance impact on signal integrity and power loss in the specific circuit topology.

Part Context

This part belongs to the B82720H series of common mode chokes manufactured by EPCOS (TDK). These components are engineered for data line protection, offering compact solutions for noise reduction in environments where space is limited but effective filtering is critical for signal quality.

Replacement Considerations

Consult official substitution lists for equivalent parts within the B82720H family or alternative manufacturers. Verify that any substitute matches the 28 mH inductance, 400 mA current rating, and 42 V AC voltage rating to ensure functional equivalence.
