744031220 Description

Short technical summary and product information.

The Würth Elektronik 744031220 is a surface-mount, shielded drum core wirewound inductor from the WE-TPC series. It offers a nominal inductance of 22 µH with a ±30% tolerance, measured at 100 kHz and 100 mV. The component is designed for power applications requiring a compact, shielded solution.

 

Key electrical specifications include a typical DC resistance of 410 mOhm and a maximum of 450 mOhm at 20°C. The rated current is 510 mA based on a 30K temperature rise, and the typical saturation current is 360 mA. The self-resonant frequency is 26 MHz.

 

The inductor is housed in a nonstandard 3816 package with dimensions of 3.80 mm x 3.80 mm and a seated height of 1.65 mm. It is constructed with a ferrite core and is fully shielded for reduced electromagnetic interference. The operating temperature range is -40°C to +125°C.
