103R-120J

Overview

The Delevan 103R-120J is a surface-mount RF inductor from the 103/R series, designed for high-frequency applications. It features an unshielded construction with a ferrite core and nonstandard two-lead termination. The component provides a nominal inductance of 12 nH with a tolerance of ±10%. It supports a maximum DC current of 1.19 A and exhibits a maximum DC resistance of 69 mOhms. The self-resonant frequency reaches 750 MHz, with a minimum Q factor of 30 at 25 MHz. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded SMD design optimized for RF signal integrity
• Ferrite core construction for stable high-frequency performance
• Nonstandard two-lead termination for flexible PCB mounting

Applications

• RF matching networks
• High-frequency filtering circuits
• Impedance matching stages

Procurement Notes

Verify RoHS compliance status as documentation may indicate non-compliance depending on production batch. Confirm lead availability through authorized distributors, as stock levels fluctuate. Ensure ordering suffixes match specific reel quantities if required by assembly equipment. Cross-reference datasheet revisions to confirm terminal plating and material specifications before final procurement.

Selection Notes

Select this component for low-inductance RF applications requiring minimal shielding interference. The 12 nH value suits VHF/UHF bands where parasitic effects must be minimized. Consider the 1.19 A current rating for power handling needs. The unshielded type allows for custom magnetic field routing but requires careful layout to prevent crosstalk compared to shielded alternatives.

Part Context

Part of the Delevan 103/R series, which offers various inductance values in a consistent 1010 package footprint. This series targets general-purpose RF and microwave circuits. The 103R-120J represents the lower end of the inductance spectrum within this family, providing high self-resonant frequencies suitable for broadband applications.
