103R-470J

Overview

The Delevan 103R-470J is an unshielded surface-mount RF inductor with a nominal inductance of 47 nH and a tolerance of ±5%. It features a maximum DC resistance of 145 mΩ and supports a maximum DC current of 820 mA. The component has a self-resonant frequency of 1.22 GHz and a minimum Q factor of 42. 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
• High self-resonant frequency suitable for RF applications
• Standard SMD/SMT termination style

Applications

• RF circuit design
• PCB mount implementations

Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and Delevan. Confirm RoHS compliance status through official documentation. Ensure the ordering suffix matches the required tolerance, as 'J' indicates ±5% while 'K' denotes ±10%. Validate that the unshielded variant aligns with your electromagnetic compatibility requirements.

Selection Notes

Select this component when a low-inductance value near 47 nH is required for high-frequency signal paths. The unshielded design necessitates careful layout to prevent coupling with adjacent traces. Verify that the 820 mA current rating exceeds the operational peak current to avoid saturation or thermal issues in the target application.

Part Context

This part belongs to the 103/R series of fixed RF inductors manufactured by Delevan. The series offers various inductance values within a standardized 1008 (2520 metric) package footprint. These components are designed specifically for radio frequency applications requiring stable performance at high frequencies.

Replacement Considerations

The 103R-470KS serves as a direct substitute with identical electrical parameters but a ±10% tolerance instead of ±5%. Other members of the 103R series may be considered if different inductance values are acceptable.
