7443763540220

The Würth Elektronik 7443763540220 is a 22 µH shielded power inductor from the WE-HCFT series. It is designed for through hole mounting with a nonstandard package measuring 41.00mm x 36.00mm x 35.00mm. The inductor uses a manganese zinc ferrite core and features wire leads for termination. Key electrical specifications include an inductance of 22 µH ±20% measured at 100 kHz/10 mA, a maximum DC resistance of 3.2 mΩ (typical 2.63 mΩ), a rated current of 40.6 A based on a 50 K temperature rise, and a typical saturation current of 42 A at 30% inductance drop. The self-resonant frequency is 9 MHz typical, and the operating voltage is 250 V. The component operates over a temperature range of -40°C to +125°C and is qualified to AEC-Q200 Grade 1, making it suitable for automotive and high-reliability applications. The shielded construction helps reduce electromagnetic interference. The part is RoHS, REACH, and halogen free compliant, with MSL level 1.
