103R-102KS

Overview

The Delevan 103R-102KS is an unshielded surface-mount RF inductor with a nominal inductance of 1 µH and a tolerance of ±10%. It features a maximum DC resistance of 0.54 Ω and supports a maximum DC current of 425 mA. The component exhibits 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 construction suitable for general-purpose RF applications
• Surface-mount design for automated PCB assembly
• Standard terminal configuration for reliable connectivity

Applications

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

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by other entities. Confirm RoHS compliance status through official documentation. Ensure the ordering suffix matches the required reel packaging format. Validate that the component meets all electrical specifications for the intended RF application before finalizing procurement.

Selection Notes

Select this component when a 1 µH inductance value is required for SMD RF designs. Consider the 425 mA current rating and 0.54 Ω DCR for power handling needs. The 103/R series offers a compact footprint suitable for space-constrained layouts. Verify compatibility with operating frequencies below the 145 MHz self-resonant point.
