Procurement Notes

Verify the specific ordering suffix to confirm compliance status. The standard 15M121K designation typically indicates lead (Pb) composition, whereas the LF suffix denotes RoHS compliance. Confirm terminal plating specifications and package dimensions against your assembly requirements before procurement.

Selection Notes

Select this component when an unshielded axial inductor with a 1.2 µH value is required for RF applications. Ensure the 650 mA current rating and 0.42 Ω DC resistance meet circuit constraints. Verify that the lack of shielding aligns with electromagnetic interference requirements.

Part Context

This part belongs to the Gowanda 15M series of molded unshielded RF coils. These components are designed for through-hole mounting and are commonly utilized in high-reliability sectors such as aerospace and defense where robust magnetic components are necessary.

Replacement Considerations

Cross-reference with other Gowanda 15M series variants or equivalent axial RF inductors from other manufacturers. Ensure matching inductance, tolerance, current rating, and physical dimensions for direct substitution.
