Procurement Notes

Verify the specific suffix U041 against official EPCOS/TDK documentation to confirm pin configuration and mechanical tolerances. Ensure the selected variant matches the required 10A current rating and 250VAC insulation class for the target application environment. Cross-reference datasheet revisions to guarantee compatibility with current manufacturing standards.

Selection Notes

Select this component when designing systems requiring robust common-mode noise reduction for dual-conductor power lines. The 6.25 mH inductance offers significant attenuation for high-frequency interference while maintaining low DC resistance to minimize power loss. Consider the through-hole package size and operating temperature range when defining the thermal and spatial constraints of the final assembly.

Part Context

This component belongs to the B82725 series of power line chokes manufactured by EPCOS (TDK Electronics). These devices are engineered for reliable operation in demanding industrial and commercial environments. The series provides standardized solutions for electromagnetic compatibility, ensuring stable power delivery and protection against voltage spikes in various electrical systems.

Replacement Considerations

Consult official TDK/EPCOS substitution guides for verified alternatives. Generic cross-references may not match the specific 6.25 mH inductance or 10A current rating. Verify that any substitute maintains the same ring core construction and through-hole mounting specifications to ensure physical and electrical compatibility.
