103R-151FS

Overview

The Delevan 103R-151FS is an unshielded surface-mount RF inductor with a nominal inductance of 150 nH and a tolerance of 1%. It features a maximum DC resistance of 175 mOhms and supports a maximum DC current of 745 mA. The component exhibits a minimum Q factor of 40 and a self-resonant frequency of 650 MHz. Its physical dimensions are 2.92 mm in length, 2.66 mm in width, and 2.41 mm in height.

Feature Summary

• Unshielded construction for minimal magnetic interference
• High self-resonant frequency suitable for RF applications
• Standard SMD termination for PCB mounting

Applications

• RF circuit design
• Signal processing systems
• Wireless communication modules

Procurement Notes

Verify the specific manufacturer datasheet to confirm exact electrical tolerances and thermal ratings before integration. Ensure compatibility with standard SMT reflow processes. Confirm RoHS compliance status through official documentation. Validate that the 175 mOhm DC resistance meets system power loss requirements.

Selection Notes

Select this component when a compact 150 nH inductance is required for high-frequency RF environments. The unshielded design suits applications where magnetic coupling with adjacent components must be minimized. Verify that the 745 mA current rating aligns with the operational load. Consider the 650 MHz self-resonant frequency limit for signal integrity.

Part Context

This part belongs to the Delevan 103R series of RF inductors. It shares the same 1008 (2520 metric) package footprint as other variants in the family, such as the 103R-151F. The 'S' suffix typically denotes specific packaging or handling characteristics within the manufacturer's catalog.

Replacement Considerations

The 103R-151F is a confirmed substitute with identical electrical parameters and physical dimensions. Cross-reference the specific suffix requirements with the manufacturer to ensure packaging consistency.
