7443330470 Description

Short technical summary and product information.

The Würth Elektronik 7443330470 is a 4.7 µH, ±20% tolerance, shielded SMT power inductor from the WE-HCC (High Current Cube) series. This component is designed for high current applications, featuring a low DC resistance of 9.4 mΩ typical and 9.9 mΩ maximum. The rated current is 11.3 A maximum, based on a 40 K temperature rise (I_RP,40K), with a typical saturation current of 15 A at 10% inductance drop and 17.9 A at 30% inductance drop.

 

This inductor is qualified to AEC-Q200 Grade 1, making it suitable for automotive applications. It is RoHS, REACH, and Halogen Free compliant. The component is housed in a nonstandard SMT package with dimensions of 10.9 mm x 10.0 mm x 9.7 mm. The operating temperature range is -40°C to +125°C, with an ambient temperature range for rated current of -40°C to +75°C. The self-resonant frequency is 49 MHz typical, and the maximum operating voltage is 120 V.
