74404042010 Description

Short technical summary and product information.

The 74404042010 is a 1 µH semi-shielded power inductor from Würth Elektronik's WE-LQS series. It has a ±30% inductance tolerance tested at 100 kHz / 1 V. The DC resistance is 27 mΩ ±20% at 20 °C. The rated current is 3.2 A maximum based on a 40 K temperature rise, with a typical saturation current of 4.8 A (30% inductance drop). The self-resonant frequency is 120 MHz typical, and the maximum operating voltage is 120 V DC. It operates over -40 °C to +125 °C.

 

This inductor uses a ferrite core with wirewound construction and is semi-shielded. It is surface mounted in a nonstandard package with dimensions 4.00 mm x 4.00 mm and a height of 1.80 mm. The component is AEC-Q200 qualified (Grade 1) and has Moisture Sensitivity Level 1 (unlimited). It complies with RoHS, REACH, and Halogen Free requirements.

 

Applications include power management circuits such as DC-DC converters, automotive electronics, and general filtering in compact designs.
