The Würth Elektronik 744773122 is a WE-PD2 series SMT power inductor featuring a drum core wirewound construction with a ferrite core. It offers an inductance of 22µH with ±20% tolerance, rated for a continuous current of 1A (ΔT=40K) and a saturation current of 1.22A typical. The DC resistance is 0.261Ω typical and 0.37Ω maximum at 20°C. This unshielded inductor has a self-resonant frequency of 20MHz typical and a maximum operating voltage of 120V DC.
The component is housed in a nonstandard SMD package with dimensions 4.5mm x 3.2mm x 4.0mm. It operates over a temperature range of -40°C to +125°C, with an ambient temperature range for rated current of -40°C to +85°C. The inductor is RoHS, REACH, and halogen free compliant, with MSL level 1 (unlimited).
Typical applications include power supply circuits, DC-DC converters, and general filtering in electronic equipment where a compact surface mount power inductor is required.
