106-181F

Overview

The Delevan 106-181F is an unshielded surface-mount RF inductor from the 1008/R series. It features a nominal inductance of 180 nH with a tight tolerance of ±1%. The component utilizes a ferrite core and is housed in a 1008 (2520 metric) package, measuring 2.92 mm in length, 2.66 mm in width, and 2.41 mm in height. It supports a maximum DC current of 1.12 A and exhibits a maximum DC resistance of 120 mOhms. The self-resonant frequency is specified at 550 MHz, with a minimum Q factor of 40.

Feature Summary

• Unshielded construction optimized for high-frequency RF signal integrity
• Ferrite core design ensures stable inductance characteristics
• Surface-mount termination facilitates automated PCB assembly

Applications

• RF circuit filtering
• Impedance matching networks
• High-frequency signal processing

Procurement Notes

Verify RoHS compliance status prior to procurement, as documentation indicates non-compliance. Confirm that the 1008 package dimensions align with target PCB footprint requirements. Ensure operating conditions remain within the specified temperature range of -55°C to +125°C. Validate that the 1.12 A current rating meets system peak load demands without saturation.

Selection Notes

Select this component for applications requiring precise 180 nH inductance with minimal parasitic effects due to its unshielded nature. Consider the 120 mOhm DCR for efficiency calculations in power-sensitive RF paths. The 550 MHz self-resonant frequency defines the upper operational limit for effective inductive behavior.

Part Context

This part belongs to the 1008/R series of fixed RF inductors manufactured by API Delevan. It is designed specifically for radio frequency applications where low profile and high Q factors are critical. The series offers various inductance values within the standard 1008 SMD footprint.

Replacement Considerations

S1008-181K is a shielded alternative within the same series. Verify if shielding requirements differ between designs.
