7447779122 Description

Short technical summary and product information.

The Würth Elektronik 7447779122 is a shielded SMT power inductor from the WE-PD series. It offers an inductance of 22 µH with ±20% tolerance, measured at 1 kHz and 250 mV. The inductor is rated for a current of 1.41 A (ΔT=40 K) and a maximum DC resistance of 110 mΩ.

 

Designed for robust performance, this inductor supports a saturation current of 1.7 A typical at 10% inductance drop and 2.1 A typical at 30% drop. The self-resonant frequency is 17 MHz typical, and the maximum operating voltage is 120 V. It features a ferrite core and is fully shielded for EMI reduction.

 

This component is AEC-Q200 Grade 1 qualified, making it suitable for automotive applications. It also complies with RoHS and REACH directives and is halogen-free per JEDEC JS709B. The operating temperature range is -40°C to +125°C, with an ambient temperature up to +85°C for rated current.

 

The inductor is housed in a nonstandard 7345 package (7.3 mm x 7.3 mm x 4.5 mm) and is designed for surface mount assembly. It has a moisture sensitivity level of 1 (unlimited) and is suitable for high-reliability environments.
