• Surface-mount electronic assemblies

Procurement Notes

Verify the specific suffix designation against official API Delevan documentation to confirm exact tolerance and electrical characteristics. Ensure that the procurement source provides valid traceability data regarding lead-free status and RoHS compliance, as these attributes are critical for regulatory adherence in modern manufacturing environments.

Selection Notes

Select this component when a 12 µH inductance value with ±2% precision is required for RF or general-purpose applications. Consider the 1611 footprint dimensions and the 4 Ω DC resistance limit during PCB layout. Evaluate the 150 mA current rating to ensure it meets the operational requirements of the target circuit without saturation.

Part Context

This part belongs to the Series 106 family of surface-mount inductors manufactured by API Delevan. The series includes various inductance values tailored for RF and general-purpose uses. The 106-123K variant specifically targets applications requiring higher inductance stability compared to standard general-purpose chokes.

Replacement Considerations

Cross-reference with other Series 106 variants such as 106-153K or 106-183K if different inductance values are needed while maintaining the same package and construction style.
