103R-121G

Overview

The Delevan 103R-121G is an unshielded surface-mount RF inductor with a nominal inductance of 120 nH and a tolerance of ±2%. It features a maximum DC resistance of 125 mΩ and supports a maximum DC current of 880 mA. The component has a standard SMD/SMT termination style and measures 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. It belongs to the 103/R series and is designed for RF applications.

Feature Summary

Unshielded construction suitable for general RF circuit integration
High precision inductance tolerance for stable signal performance
Compact non-standard footprint optimized for space-constrained PCB layouts

Applications

RF signal processing circuits
Impedance matching networks
Filter design in radio frequency systems

Procurement Notes

Verify the manufacturer designation carefully, as API Delevan assets were acquired by EPCOS (TDK). Confirm that the specific part number corresponds to the original Delevan manufacturing specifications rather than a generic equivalent. Ensure the ordering suffix matches the required reel quantity and packaging format to avoid supply chain discrepancies during procurement.

Selection Notes

Select this component when a low-inductance value with tight tolerance is required for high-frequency RF paths. The unshielded design necessitates careful layout consideration to minimize electromagnetic interference with adjacent traces. Evaluate the 880 mA current rating against peak operational loads to ensure thermal stability and prevent saturation effects in the target application environment.

Part Context

This component is part of the Delevan 103/R series of surface-mount RF inductors. These components are characterized by their small physical dimensions and suitability for automated pick-and-place assembly processes. The series provides various inductance values tailored for different RF frequency bands and impedance requirements.
