105-392F

Overview

The Delevan 105-392F is a fixed surface-mount RF inductor with an inductance of 3.9 µH and a tolerance of ±1%. It features a maximum DC resistance of 2.8 Ohms and a rated current of 185 mA. The component operates within a temperature range of -55°C to 125°C and has a self-resonant frequency of 57 MHz.

Feature Summary

Unshielded chip design for general-purpose RF applications
Epoxy encapsulated construction for environmental protection
Iron core material providing stable inductance characteristics

Applications

RF signal processing circuits
General purpose inductors in electronic assemblies
Surface mount PCB integration

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead availability through authorized distributors, noting potential discontinuation risks associated with older API Delevan series components. Ensure the specific suffix matches required specifications.

Selection Notes

Select this component for unshielded RF applications requiring precise 3.9 µH inductance. Consider the 2.8 Ohm DC resistance and 185 mA current rating against circuit requirements. Verify package compatibility for surface mount assembly processes.

Part Context

Part of the 105/R series from API Delevan, designed for surface mount technology. This series utilizes iron cores and epoxy encapsulation to provide reliable performance in radio frequency environments.

Replacement Considerations

The 105-392FS is a documented variant with identical electrical parameters but potentially different packaging or termination styles. Verify physical dimensions and terminal configurations before substitution.
