7443630420 Description

Short technical summary and product information.

The Würth Elektronik 7443630420 is a WE-HCF series SMT high current shielded inductor designed for demanding power applications. It features a drum core wirewound construction with a manganese zinc ferrite (MnZn) core, providing an inductance of 4.2µH at 100kHz/10mA with ±15% tolerance.

 

This inductor is rated for a continuous current of 24A (ΔT=50K) and up to 27A (ΔT=40K per IEC 62024-2-2020). Saturation current is 34A typical at 10% inductance drop and 38A typical at 30% drop. DC resistance is 3.34mΩ maximum, and the self-resonant frequency is 24MHz typical. Maximum operating voltage is 150V.

 

The component is shielded for EMI reduction and is qualified to AEC-Q200 for automotive applications. It operates over a temperature range of -40°C to +125°C and is RoHS and REACH compliant with MSL 1. The package is a nonstandard surface mount format.
