The Würth Elektronik 74457122 is a surface mount power inductor from the WE-PD4 series. It features a drum core wirewound construction with a ferrite core and is unshielded. Key electrical specifications include an inductance of 22 µH at 100 kHz/1 V with ±15% tolerance, a rated current of 4 A (ΔT=40K), and a typical saturation current of 6.5 A. DC resistance is 0.039 Ω typical and 0.047 Ω maximum. The self-resonant frequency is 14 MHz typical. Operating voltage is 120 V DC maximum.
The inductor operates over a temperature range of -40°C to +125°C and has an ambient temperature range of -40°C to +85°C for rated current. It is RoHS, REACH, and Halogen Free compliant with MSL 1 (unlimited). The package dimensions are 22.00 mm x 15.00 mm x 7.80 mm in a nonstandard SMD form factor.
This component is suitable for power supply filtering, DC-DC converter output chokes, and high current power management circuits where low DC resistance and high current handling are required.
