Fixed Inductors Procurement Notes

Verify component authenticity through official TDK channels or authorized distributors. Confirm RoHS compliance and AEC-Q200 qualification status if required for automotive use. Check datasheet revisions for potential marking or material changes. Ensure storage conditions maintain component integrity prior to assembly.

Fixed Inductors Selection Notes

Select this component for high-frequency circuits requiring stable inductance. Consider the 280 mA current rating for power handling. Verify footprint compatibility with 1210 SMD package dimensions. Evaluate self-resonant frequency constraints against target signal frequencies.

Fixed Inductors Part Context

Part of the B82422A SIMID series, designed for surface mount technology. Manufactured by EPCOS, now part of TDK Electronics. Utilizes copper base material with silver and tin plating. No leaching during wave soldering ensures reliable interconnects.

Fixed Inductors Replacement Considerations

B82422A3221K108 offers similar specifications with ±10% tolerance instead of ±5%. Both share identical physical dimensions and electrical characteristics except for tolerance variance.
