103-822GS

Overview

The Delevan 103-822GS is a surface-mount RF inductor from the 103/R series, designed for high-frequency applications. It features an 8.2 µH nominal inductance with a tight ±2% tolerance and a maximum DC resistance of 2.5 Ohms. The component supports a maximum DC current of 195 mA and operates within a temperature range of -55°C to +125°C. Measuring 2.54 mm x 2.54 mm x 1.91 mm, it utilizes an unshielded iron core construction.

Feature Summary

• Unshielded chip design optimized for RF signal integrity
• High stability across extended industrial temperature ranges
• Compact footprint suitable for dense PCB layouts

Applications

• RF circuit filtering
• Impedance matching networks
• High-frequency signal processing

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package type availability, as listings vary between cut tape and reel formats. Ensure the specific suffix matches project requirements for tolerance and current ratings. Cross-reference datasheet revisions to confirm electrical parameters align with design specifications before finalizing procurement orders.

Selection Notes

Select this component for applications requiring precise inductance values with minimal deviation. The unshielded nature requires careful layout consideration to prevent magnetic interference with nearby traces. Evaluate thermal management needs given the operating temperature limits and current handling capabilities during initial design phases.

Part Context

Part of the 103/R series, this inductor represents Delevan's standard SMD RF line. It shares dimensional similarities with other 103 variants but differs in electrical characteristics such as Q factor and self-resonant frequency. The series is widely used in telecommunications and consumer electronics for stable RF performance.
