105R-121H

Overview

The Delevan 105R-121H is a surface-mount RF inductor with an inductance of 120 nH and a tolerance of 3%. It features a maximum DC resistance of 140 mOhms and a rated current of 830 mA. The component utilizes an unshielded design within a nonstandard footprint, suitable for PCB mounting.

Feature Summary

Unshielded construction for minimal magnetic interference
Surface-mount technology for automated assembly
High-current capability relative to standard RF inductors

Applications

RF circuit filtering
Impedance matching networks
Signal processing circuits

Procurement Notes

Verify the specific manufacturer designation as the part number may be associated with API Delevan or similar entities. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies. Ensure the nonstandard footprint matches the target PCB layout before ordering.

Selection Notes

Select this component when a low-inductance, high-current SMD solution is required. The unshielded design necessitates careful placement to avoid coupling. Verify that the 830 mA current rating meets the application's peak load requirements without saturation.

Part Context

This part belongs to the 105R series of fixed inductors from Delevan. It is categorized under RF Inductors - SMD. The series offers various inductance values with consistent physical characteristics for standardized RF board designs.

Replacement Considerations

The 105R-121G is a variant with potentially different tolerances or packaging. Cross-reference electrical parameters such as DCR and current rating before substitution. Verify mechanical footprint compatibility to ensure direct replacement feasibility.
