Procurement Notes

Verify the manufacturer part number against official TDK/EPCOS documentation to ensure authenticity. Confirm that the received component matches the specified rectangular package dimensions and terminal configuration. Check for RoHS compliance markings as indicated in the product description. Ensure storage conditions respect the specified operating temperature limits to maintain component integrity before installation.

Selection Notes

Select this component when a 1 mH inductance value is required for power line chokes or sine-wave filters. Consider the 0.43 Ω DC resistance and current handling capabilities relative to the circuit requirements. The rectangular PCB mount form factor and specific dimensional constraints must align with the available board space. Verify compatibility with the intended operating temperature range of -40 °C to 125 °C.

Part Context

This component belongs to the B82614 series of power line chokes produced by EPCOS, now part of TDK Electronics.
