74455122 Description

Short technical summary and product information.

The Würth Elektronik 74455122 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. The inductor offers an inductance of 22 µH with ±20% tolerance. It is rated for a continuous current of 0.8 A (ΔT=15K) and has a saturation current of 0.7 A typical (ΔL/L<10%). The DC resistance is 0.255 Ω typical and 0.37 Ω maximum. The self-resonant frequency is 16 MHz typical. The component can operate at voltages up to 120 V DC and over a temperature range of -40°C to +125°C. It comes in a nonstandard SMD package with dimensions of 6.60 mm x 4.45 mm x 2.92 mm. The inductor is compliant with RoHS, REACH, and Halogen Free standards, and has a moisture sensitivity level of 1 (unlimited). Designed for general electronic equipment, this inductor is suitable for power supply filtering, DC-DC converters, and other surface mount power applications.
