744766118

Fixed Inductors Overview

The Würth Elektronik 744766118 is an unshielded wirewound RF inductor from the WE-GF series, packaged in a 1812 (4532 metric) surface-mount footprint. It features a nominal inductance of 18 µH with a tolerance of ±20%. The component has a maximum DC resistance of 2.8 ohms and a self-resonant frequency of 15 MHz. It supports a maximum DC current rating of 190 mA and operates within a temperature range of -40°C to +85°C.

Fixed Inductors Feature Summary

• Unshielded wirewound construction for minimal magnetic interference
• Drum core design optimized for RF applications
• Surface-mount package suitable for automated PCB assembly

Fixed Inductors Applications

• RF signal filtering circuits
• Impedance matching networks
• General-purpose RF chokes

Fixed Inductors Procurement Notes

Verify the specific suffix codes on the ordering label against the official datasheet to confirm exact inductance tolerance and packaging configuration. Ensure that the procurement documentation explicitly references the 1812 package dimensions and the 190 mA current rating to avoid substitution errors with similar high-current variants.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is required to prevent magnetic coupling issues in dense layouts. The 18 µH value and 190 mA rating suit low-power RF stages. Consider the 15 MHz self-resonant frequency limit to ensure operation remains below the resonant point for effective filtering performance.

Fixed Inductors Part Context

This part belongs to the WE-GF series of fixed inductors designed for general RF use. It complements other Wurth components by providing an unshielded alternative to shielded types, offering distinct electromagnetic characteristics for circuit designers managing stray field interactions in sensitive analog or radio frequency pathways.
