105-182G

Overview

The Delevan 105-182G is a fixed surface-mount inductor with an inductance of 1.8 µH and a tolerance of ±5%. It features a maximum DC current rating of 250 mA and a maximum DC resistance of 1.5 Ohms. The component has a minimum Q factor of 25 and a self-resonant frequency of 90 MHz. It utilizes an unshielded design with standard nonstandard two-lead termination for PCB mounting.

Feature Summary

• Unshielded wirewound construction for RF applications
• Standard nonstandard two-lead SMD termination
• Ferrite core material

Applications

• RF filtering circuits
• General electronic circuit signal conditioning
• Power supply choke applications

Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be sourced under various corporate identifiers. Confirm RoHS compliance status directly with the supplier documentation, as regulatory markings can vary by production batch. Ensure the nonstandard lead configuration matches the target PCB footprint requirements before finalizing procurement orders to avoid assembly mismatches.

Selection Notes

Select this component for designs requiring a 1.8 µH inductance with tight 5% tolerance in RF environments. The 250 mA current rating suits low-power signal paths rather than high-current power stages. Consider the 90 MHz self-resonant frequency limit when selecting for higher frequency operations. The unshielded nature requires layout consideration to minimize electromagnetic interference coupling with nearby traces.

Part Context

This part belongs to the 105/R series of RF inductors manufactured by Delevan. These components are designed for surface mount technology (SMT) integration into printed circuit boards. The series typically offers fixed inductance values optimized for radio frequency signal processing and impedance matching tasks within consumer and industrial electronics.
