105R-682K

Overview

The Delevan 105R-682K is a fixed, unshielded RF inductor designed for surface-mount technology (SMD) applications. It features a ferrite core and provides an inductance of 6.8 µH with a tolerance of ±10%. The component supports a maximum DC current of 160 mA and has a maximum DC resistance of 3.8 Ohms. It operates within a temperature range of -55°C to +125°C and exhibits a self-resonant frequency of 42 MHz.

Feature Summary

• Unshielded construction utilizing a ferrite core material
• Designed for surface-mount PCB integration
• Capable of operation across extended industrial temperature ranges

Applications

• RF choke circuits
• Signal filtering in radio frequency systems
• General-purpose RF inductive components

Procurement Notes

Verify RoHS compliance status carefully, as specific variants may differ. Confirm availability through authorized distributors, noting that some listings indicate restricted supply or end-of-life status. Ensure the ordering suffix matches the required tolerance and packaging specifications before finalizing procurement orders.

Selection Notes

Select this component when an unshielded inductor is required for RF applications. Consider the 160 mA current rating and 3.8 Ohm DCR limits against circuit requirements. Compare against shielded alternatives if electromagnetic interference mitigation is necessary for the specific design environment.

Part Context

This part belongs to the 105/R series of fixed inductors manufactured by Delevan. It is categorized under RF Inductors - SMD within the broader inductors, chokes, and coils product family. The component is distinct from shielded series like the S1812R due to its open magnetic structure.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs using equivalent electrical parameters such as inductance, current rating, and physical footprint.
