103R-181GS

Overview

The Delevan 103R-181GS is an unshielded surface-mount RF inductor with a nominal inductance of 180 nH and a tolerance of ±2%. It features a maximum DC resistance of 0.278 Ohms and supports a maximum DC current of 695 mA. The component exhibits a minimum Q factor of 22 and operates at a self-resonant frequency of 450 MHz. Housed in a compact 103 (2520 metric) package measuring 2.54 mm by 2.54 mm with a height of 1.91 mm, it utilizes standard SMD/SMT termination for PCB mounting.

Feature Summary

Unshielded construction designed for high-frequency radio frequency applications
Surface-mount technology compatible with automated PCB assembly processes
Standard termination configuration for reliable circuit board integration

Applications

High-frequency RF circuits
Signal filtering networks
Impedance matching stages

Procurement Notes

Verify the specific manufacturer designation against official documentation to confirm compliance with RoHS standards, as conflicting records exist regarding this component's regulatory status. Ensure that the ordering suffix corresponds precisely to the required tolerance and packaging specifications. Cross-reference the part number with authorized distributors to validate authenticity and secure appropriate technical support during the acquisition process.

Selection Notes

Select this component when a low-inductance value near 180 nH is required for RF signal paths. Consider the 695 mA current rating and 0.278 Ohm resistance for power handling constraints. Evaluate the 450 MHz self-resonant frequency to ensure operation remains below the resonance point. Confirm that the 103 package dimensions fit within the available PCB real estate constraints.

Part Context

This component belongs to the 103/R series of fixed inductors manufactured by Delevan. The series provides various inductance values within the same 103 footprint, allowing for design flexibility while maintaining consistent mechanical mounting parameters across different circuit requirements.
