Fixed Inductors Procurement Notes

This component is officially obsolete and no longer manufactured by TDK. Procurement must rely on existing stock or authorized distributors holding remaining inventory. Verify part authenticity carefully as end-of-life items may have varying storage conditions. Ensure compatibility with replacement components before finalizing orders.

Fixed Inductors Selection Notes

Select this component only if legacy design compatibility is required. For new designs, consider the B82422A3561K100 as a direct substitute within the same manufacturer portfolio. Evaluate thermal performance at 200 mA rating and ensure PCB space accommodates the 1210 footprint. Confirm that the 1.2 ohm DCR meets circuit loss requirements.

Fixed Inductors Part Context

Part of the EPCOS/TDK SIMID line of miniaturized shielded and unshielded inductors. Designed for high-frequency applications requiring stable inductance values. The B82412A series utilizes ceramic cores for low loss and high Q factors at RF frequencies. This specific model represents a standard value in the 560 nH range for compact SMD layouts.
