103R-181H

Overview

The Delevan 103R-181H is an unshielded surface-mount RF inductor with a nominal inductance of 180 nH and a tolerance of 3%. It features a maximum DC resistance of 200 mOhms and supports a maximum DC current of 695 mA. The component has a minimum Q factor of 30 and a self-resonant frequency of 700 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded ferrite core construction for efficient power transfer
• Surface-mount design suitable for PCB mounting
• High self-resonant frequency capability

Applications

• RF circuit filtering
• Compact electronic circuits
• Signal processing applications

Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and generic Delevan. Confirm RoHS compliance status through official documentation. Ensure the ordering suffix matches the required reel quantity, typically 100 units per reel for this series. Cross-reference the datasheet to confirm the exact DC resistance value, as some listings indicate variations.

Selection Notes

Select this component when a low-profile, unshielded inductor is required for high-frequency RF applications. The 180 nH value and 700 MHz self-resonant frequency make it suitable for specific signal paths. Consider the 695 mA current rating against the circuit's operational requirements. The standard SMD package facilitates automated assembly processes.
