Overview
The Delevan 105R-121F is a fixed surface-mount inductor with an inductance of 120 nH and a tolerance of 10%. It supports a maximum DC current of 830 mA and has a maximum DC resistance of 140 mOhms. The component features an unshielded design suitable for RF applications.
Feature Summary
- Unshielded surface-mount construction
- High-frequency RF performance capability
Applications
- RF circuits
Procurement Notes
Verify the specific manufacturer designation, as sources reference both API Delevan Inc. and generic API branding. Confirm RoHS compliance status (RoHS3) and lead-free termination details against the official datasheet before procurement to ensure regulatory alignment.
Selection Notes
Select this component for high-frequency applications requiring low inductance values. Ensure the PCB layout accommodates the non-standard two-lead form factor. Verify that the 830 mA current rating meets the circuit's operational requirements without saturation.
Part Context
This part belongs to the Delevan fixed inductor lineup, designed for electronic filtering and energy storage. It utilizes an unshielded architecture typical for specific RF signal paths where magnetic interference coupling is managed by board layout rather than physical shielding.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 120 nH value, 830 mA current rating, and 140 mOhms DCR specifications with other manufacturers' RF inductor catalogs.
FAQ
Is the 105R-121F shielded?
