7447779002 Description

Short technical summary and product information.

The Würth Elektronik 7447779002 is a shielded wirewound power inductor from the WE-PD series. It features a ferrite core and drum core construction, designed for surface mount assembly in a nonstandard 7345 package. The inductor offers 2.2 µH inductance with ±20% tolerance, tested at 1 kHz / 250 mV.

 

Electrically, the component provides a rated current of 4.2 A at ΔT=40K (IEC 62024-2-2020, Class C) and a performance rated current of 6.2 A. Saturation current is 6 A typical at 10% inductance drop and 7.4 A typical at 30% drop. DC resistance is 16 mΩ typical and 20 mΩ maximum. The self-resonant frequency is 60 MHz typical, and maximum operating voltage is 120 V.

 

The inductor operates over -40°C to +125°C and is AEC-Q200 Grade 1 qualified for automotive applications. It is RoHS, REACH, and Halogen Free compliant, with MSL 1 (unlimited). The component is supplied in tape and reel packaging.
