105R-822J

Overview

The Delevan 105R-822J is a fixed surface-mount inductor with an inductance of 8.2 µH and a tolerance of ±10%. It features a non-shielded drum core wirewound construction using ferrite material. The component has a maximum DC resistance of 5 Ohms and a rated current of 135 mA. It operates within a temperature range of -55°C to 125°C, with a self-resonant frequency of 40 MHz and a Q factor of 40 at 7.9 MHz.

Feature Summary

• Non-shielded drum core wirewound design for RF applications
• High thermal stability across extended operating temperatures
• Ferrite core material ensuring stable inductance characteristics

Applications

• RF circuit filtering
• Signal processing networks
• Impedance matching circuits

Procurement Notes

Verify the specific suffix 'KS' or standard packaging against the required reel quantity. Confirm RoHS compliance status as some variants may differ. Check lead availability and moisture sensitivity level requirements before integration into the assembly process.

Selection Notes

Select this component for high-frequency applications requiring 8.2 µH inductance with moderate current handling. Ensure the 5 Ohm DCR fits the power loss constraints. Verify that the non-shielded nature does not interfere with nearby sensitive components due to potential magnetic field emission.

Part Context

This part belongs to the 105/R series of unshielded surface-mount inductors manufactured by API Delevan. These components are designed for general-purpose RF and signal conditioning tasks where compact size and cost-effectiveness are prioritized over shielding requirements.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 105R series variants only if electrical parameters match exactly.
