744373240033 Description

Short technical summary and product information.

The Würth Elektronik 744373240033 is a WE-LHMI series SMT power inductor designed for high current DC/DC converter applications. It features a shielded construction with an iron powder core to minimize EMI and magnetic interference. The inductor offers 0.33 µH inductance with ±20% tolerance, a rated current of 10.5 A (ΔT=40K), and a saturation current of 11.2 A typical at 10% inductance drop. DC resistance is 8.6 mΩ maximum and 7.8 mΩ typical, ensuring low conduction losses. The self-resonant frequency is 143 MHz typical, making it suitable for switching frequencies up to the MHz range.

 

The component is housed in a 4020 surface-mount package (4.45 mm x 4.06 mm x 2.00 mm) and supports an operating temperature range of -40°C to +125°C. It is compliant with RoHS, REACH, and Halogen-Free standards, and has an MSL rating of 1 for unlimited floor life. The inductor is suitable for use in point-of-load converters, FPGA power supplies, battery-powered devices, and mainboard power circuits.
