• General-purpose surface mount inductance requirements

Procurement Notes

Verify the specific suffix J indicates the required tolerance level against official datasheets. Confirm RoHS compliance status as historical data may vary. Check for obsolescence or lifecycle changes directly from API Delevan before finalizing procurement plans.

Selection Notes

Select this component when an unshielded 1.2 µH inductor is required for space-constrained designs. Ensure the 310 mA current rating meets circuit demands. Verify that the 1 Ohm DC resistance aligns with power loss constraints in the target application.

Part Context

This part belongs to the 105/R series of fixed inductors manufactured by API Delevan. The series offers various inductance values in a compact 1008 (2520 metric) package size, designed for high-frequency signal processing tasks in electronic assemblies.

Replacement Considerations

Cross-reference with other 1.2 µH unshielded SMD inductors from API Delevan such as the 106-122G if lead-free compliance is mandatory. Verify pin compatibility and thermal performance before substituting.
