744043220 Description

Short technical summary and product information.

The Würth Elektronik 744043220 is a shielded, drum core wirewound power inductor from the WE-TPC series. It offers a nominal inductance of 22 µH with a tolerance of ±30%, measured at 100 kHz/100 mV. The component is rated for a continuous current of 925 mA (ΔT=30 K) with a typical saturation current of 700 mA (ΔL/L<35%). Maximum DC resistance is 185 mOhm, with a typical value of 160 mOhm at 20°C. Self-resonant frequency is 20 MHz typical.

Designed for surface mount assembly, the inductor measures 4.8 mm x 4.8 mm x 2.8 mm in a 4828 case size. The operating temperature range spans -40°C to +125°C. The ferrite core and shielded construction minimize electromagnetic interference, making it suitable for power supply and DC-DC converter applications.

The WE-TPC components are RoHS, REACH, and halogen-free compliant, with an MSL (Moisture Sensitivity Level) of 1 for unlimited floor life. The inductor is manufactured by Würth Elektronik eiSos GmbH & Co. KG.
