105-682H

Overview

The Delevan 105-682H is a surface-mount RF inductor designed for radio frequency applications. It features an inductance of 6.8 uH with a tight tolerance of 3%. The component has a maximum DC current rating of 160 mA and a maximum DC resistance of 3.8 Ohms. It exhibits a minimum Q factor of 50 and a self-resonant frequency of 55 MHz. The physical dimensions are 8.26 mm in length, 3.18 mm in width, and 3.68 mm in height. It utilizes a shielded ferrite core and wirewound construction.

Feature Summary

• Shielded SMD construction for reduced electromagnetic interference
• Ferrite core material optimized for RF performance
• High Q factor supporting efficient signal processing

Applications

• RF circuit filtering
• Impedance matching networks
• Radio frequency signal conditioning

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status as documentation indicates non-compliance. Validate lead-free status against specific project requirements before integration. Ensure storage conditions maintain component integrity given the sensitive nature of RF inductors.

Selection Notes

Select this component when a shielded 6.8 uH inductor with high Q is required for RF designs. Consider the 160 mA current limit and 3.8 Ohm resistance for power budget calculations. Compare against unshielded alternatives if space or cost is critical, noting the dimensional differences. Ensure the 55 MHz self-resonant frequency aligns with the target operating band.

Part Context

This part belongs to the 1331/R series of fixed inductors from Delevan. It shares design characteristics with other shielded RF inductors in the lineup but differs in specific electrical parameters like inductance and tolerance. The series is intended for general-purpose RF applications requiring stable inductance values.

Replacement Considerations

The 105-682GS is listed as a discontinued alternative within the same manufacturer portfolio. No other public substitute part numbers are confirmed for direct replacement.
