74404064033 Description

Short technical summary and product information.

The Würth Elektronik 74404064033 is a surface-mount, semi-shielded power inductor from the WE-LQS family. It offers a nominal inductance of 3.3 µH at 100 kHz/1 V, with a ±30% tolerance. The component is rated for a maximum DC current of 4.2 A (ΔT=40 K) and has a typical saturation current of 6.5 A. Its 21 mΩ DC resistance at 20°C supports efficient power delivery.

 

Designed for automotive and general electronic equipment, the inductor meets AEC-Q200 Grade 1 requirements and operates over -40°C to +125°C. The semi-shielded drum core construction uses a ferrite core, and the component is supplied in a nonstandard 6045 package. The surface-mount design measures 6.00 mm x 6.00 mm with a maximum height of 4.50 mm.

 

With a self-resonant frequency of 42 MHz and a maximum operating voltage of 120 V, this inductor is well suited for power supply circuits, DC-DC converters, and filtering applications. The part is RoHS compliant, REACH conform, and halogen free.
