108-104G

Overview

The Delevan 108-104G is a fixed surface-mount RF inductor designed for high-frequency applications. It features an inductance of 100 µH with a tight tolerance of ±2%. The component utilizes a shielded construction to minimize electromagnetic interference, making it suitable for sensitive RF circuits. It has a maximum DC resistance of 31 Ohms and supports a maximum DC current of 28 mA. The device operates within a temperature range of -55°C to +125°C and is housed in a nonstandard two-lead SMT package.

Feature Summary

• Shielded surface-mount construction for reduced electromagnetic interference
• High precision inductance with ±2% tolerance
• Wide operating temperature range for harsh environments

Applications

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

Procurement Notes

Verify the specific package dimensions against the official datasheet, as the 108 series uses a nonstandard footprint distinct from common industry sizes. Confirm that the 31 Ohm DC resistance aligns with circuit requirements. Ensure the supplier provides documentation confirming compliance with relevant military or industrial standards if required by the application environment.

Selection Notes

Select this component when precise 100 µH inductance is required in a compact shielded form factor. The low current rating of 28 mA necessitates careful consideration of bias conditions. Compare against standard packages like 1210 or 1812 only if custom footprints are permissible. The wide temperature range supports operation in demanding thermal conditions.

Part Context

This part belongs to the API Delevan fixed inductor portfolio, specifically tailored for radio frequency applications. It complements other shielded SMD inductors in the manufacturer's lineup, offering higher precision than standard tolerance variants. The product line emphasizes reliability in aerospace and defense sectors.

Replacement Considerations

Direct substitutes include the 108R-104G, which shares identical electrical specifications and shielding characteristics. Verify mechanical fit before substitution due to potential minor dimensional variances between manufacturing revisions.
