744778118 Description

Short technical summary and product information.

The Würth Elektronik 744778118 is a fixed inductor from the WE-PD series, featuring a shielded drum core wirewound construction. It offers an inductance of 18 µH at 1 kHz with a tolerance of ±20%, and is rated for a continuous current of 1.41 A. The component has a maximum DC resistance of 140 mOhm and a self-resonant frequency of 24 MHz.

 

Designed for surface mount assembly, the inductor occupies a 7.30mm x 7.30mm footprint with a height of 3.40mm. It is wound on a ferrite core and fully shielded to minimize electromagnetic interference. The operating temperature range spans -40°C to 125°C, making it suitable for demanding environments.

 

This inductor is AEC-Q200 qualified, confirming its reliability for automotive applications. It is supplied in tape and reel packaging, compatible with automated pick-and-place processes. Applications include DC-DC converters, power supplies, and EMI filtering circuits.
