103R-151G

Overview

The Delevan 103R-151G is an unshielded surface-mount RF inductor with a nominal inductance of 150 nH and a tolerance of ±2%. It features a maximum DC resistance of 175 mΩ and supports a maximum DC current of 745 mA. The component exhibits a minimum Q factor of 25 and a self-resonant frequency of 650 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 for minimal magnetic interference
• Surface-mount design for automated PCB assembly
• High self-resonant frequency suitable for RF applications

Applications

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

Procurement Notes

Verify the specific suffix (e.g., G vs KS) against official datasheets to confirm tolerance and packaging details. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as documentation may vary by production batch. Ensure the ordering quantity aligns with standard reel sizes if applicable.

Selection Notes

Select this component when a low-inductance, unshielded SMD inductor is required for high-frequency operation. The 150 nH value and 650 MHz self-resonant frequency make it suitable for specific RF bands. Consider the 745 mA current rating for power handling requirements and the 175 mΩ resistance for loss minimization in sensitive circuits.

Part Context

This part belongs to the 103R series of fixed inductors from API Delevan. The series offers various inductance values in a compact 1008 (2520 metric) package size. These components are designed for general RF applications where unshielded performance is acceptable.

Replacement Considerations

Cross-reference with other 150 nH ±2% SMD inductors in the 1008 package. Verify that substitute parts meet the 650 MHz self-resonant frequency and 745 mA current specifications. Check for equivalent Q factor and DC resistance values to ensure circuit compatibility.
