103R-100JS

Overview

The Delevan 103R-100JS is an unshielded surface-mount RF inductor with a nominal inductance of 10 nH and a tolerance of ±5%. It features a maximum DC resistance of 60 mΩ and supports a maximum DC current of 1.27 A. The component exhibits a minimum Q factor of 40 at 50 MHz and achieves a self-resonant frequency of 2.7 GHz. Its physical dimensions are 2.92 mm in length, 2.66 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded construction for minimal magnetic interference
• High self-resonant frequency suitable for RF applications
• Low DC resistance for efficient power handling

Applications

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

Procurement Notes

Verify the manufacturer designation, as sources list both Delevan and API Delevan Inc. Confirm the specific package style and termination type against your PCB footprint requirements. Ensure the component meets RoHS compliance standards if required by your manufacturing process. Cross-reference the datasheet version to confirm electrical parameters match your design specifications.

Selection Notes

Select this component for high-frequency RF designs requiring low inductance values. The unshielded design minimizes size but requires careful layout to prevent coupling. Verify that the 1.27 A current rating exceeds your circuit's peak DC load. Consider the 2.7 GHz self-resonant frequency to ensure operation remains below the resonant point for inductive behavior.
