74404020100 Description

Short technical summary and product information.

The Würth Elektronik 74404020100 is a surface-mount semi-shielded power inductor from the WE-LQS series. It features a ferrite core and wirewound construction, providing an inductance of 10 µH with a tolerance of ±20%. The component is rated for a maximum DC current of 0.5 A (based on a 40 K temperature rise) and has a typical saturation current of 0.6 A. Its DC resistance is 860 mΩ with a ±20% tolerance.

 

This inductor is designed for general electronic equipment and is AEC-Q200 qualified (Grade 1), making it suitable for automotive applications. It operates over a temperature range of -40°C to +125°C and has a self-resonant frequency of 39 MHz. The component is RoHS3 compliant, REACH unaffected, and halogen-free.

 

The 74404020100 comes in a nonstandard SMD package measuring 2.00 mm x 1.60 mm with a maximum seated height of 1.00 mm. It is semi-shielded to reduce electromagnetic interference.
