74404054015 Description

Short technical summary and product information.

The Würth Elektronik 74404054015 is a surface-mount, semi-shielded power inductor from the WE-LQS series. It features a drum core and wirewound construction with a ferrite core, providing an inductance of 1.5µH ±30% at 100kHz/1V. The component is rated for a continuous current of 4.3A (ΔT=40K) and has a saturation current of 6.9A typical (|ΔL/L|<30%). The DC resistance is 15mΩ ±20% at 20°C, and the self-resonant frequency is typically 137MHz. The operating voltage is 120V maximum.

 

The inductor is qualified to AEC-Q200 Grade 1, making it suitable for automotive applications. It is RoHS3 compliant, REACH unaffected, halogen-free, and has a moisture sensitivity level of 1 (unlimited). The operating temperature range is -40°C to 125°C, with rated current specified at ambient temperatures up to 85°C.

 

Package dimensions are 5.00mm x 5.00mm x 4.00mm (max height 4.0mm), with a supplier device package of 5040. The termination style is not explicitly stated in the datasheet but is typical for SMD inductors. The component is designed for use in power supply circuits, DC-DC converters, and other applications requiring low-profile, high-current inductors.
