105R-122H

Overview

The Delevan 105R-122H is a fixed surface-mount RF inductor with a nominal inductance of 1.2 µH and a tolerance of 3%. It features a maximum DC resistance of 1 Ohm and supports a maximum DC current of 310 mA. The component utilizes an unshielded design with two non-standard leads for PCB mounting.

Feature Summary

Unshielded wirewound construction for general-purpose RF applications
Surface-mount termination style for automated PCB assembly
High precision inductance tolerance for stable circuit performance

Applications

RF signal processing circuits
General purpose inductive filtering
Communication equipment modules

Procurement Notes

Verify availability status as the component lifecycle is listed as obsolete. Confirm specific lead configuration requirements due to the non-standard terminal design. Check RoHS compliance details against current regulatory standards before integration into new designs.

Selection Notes

Select this component for low-current RF applications requiring precise 1.2 µH inductance. Ensure the PCB layout accommodates the specific non-standard lead spacing. Consider the 310 mA current limit when designing power paths to prevent saturation or thermal issues.

Part Context

This part belongs to the Delevan fixed inductor family, specifically designed for radio frequency environments. It serves as a passive energy storage element within high-frequency signal chains, distinguishing itself through its unshielded topology and specialized lead geometry compared to standard SMD chokes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete lifecycle and unique non-standard lead specifications, direct pin-to-pin replacements may require custom adapter solutions or redesign.
