74458122 Description

Short technical summary and product information.

The Würth Elektronik 74458122 is a WE-PD4 series SMT power inductor. It features a ferrite drum core with wirewound construction, unshielded. Key electrical specifications include an inductance of 22µH at 100kHz/100mV with ±20% tolerance, a rated current of 3.5A (ΔT=40K), and a saturation current of 7A typical. DC resistance is 0.043Ω typical and 0.047Ω maximum. The self-resonant frequency is 13MHz typical. Operating voltage is 120V DC. The component is designed for surface mount assembly in a nonstandard package measuring 18.54mm x 15.24mm x 7.11mm. Operating temperature range is -40°C to +125°C. It is RoHS, REACH, and Halogen Free compliant with MSL 1. Typical applications include power supply filtering, DC-DC converters, and energy storage circuits where high current handling and low DCR are required.
