103R-102GS

Overview

The Delevan 103R-102GS is an unshielded surface-mount RF inductor with a nominal inductance of 1 µH and a tolerance of 2%. It features a maximum DC resistance of 540 mOhms and supports a maximum DC current of 425 mA. The component has a minimum Q factor of 22 and a self-resonant frequency of 145 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded SMD construction for standard RF circuit integration
• High precision 2% inductance tolerance for stable signal performance
• Compact 1010 metric footprint suitable for space-constrained PCB layouts

Applications

• RF signal filtering
• Impedance matching networks
• General RF circuit design

Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and Delevan. Confirm RoHS compliance status through official documentation before procurement. Ensure the ordering suffix matches the required tolerance and packaging specifications to avoid functional discrepancies.

Selection Notes

Select this component when a precise 1 µH inductance with tight 2% tolerance is required for RF applications. Consider the 425 mA current rating and 540 mOhm resistance for power handling needs. The unshielded design requires careful layout consideration to minimize electromagnetic interference compared to shielded alternatives.

Part Context

This part belongs to the 103/R series of fixed RF inductors manufactured by Delevan. It is designed for surface-mount technology (SMT) applications. The series offers various inductance values and tolerances to support diverse radio frequency circuit requirements.

Replacement Considerations

The 103R-102KS serves as a direct substitute within the same series, offering identical electrical characteristics but with a wider 10% tolerance instead of 2%. Verify that the looser tolerance meets the target application's precision requirements.
