7443551111 Description

Short technical summary and product information.

The Würth Elektronik 7443551111 is a WE-HCI series high current shielded wirewound inductor designed for surface mount applications. It provides an inductance of 11.3 µH at 100 kHz / 100 mV with a ±20% tolerance, and a rated inductance of 7.5 µH at full rated current (11.0 A). The component is rated for a maximum current of 11 A with a ΔT of 50 K, and a performance rated current of 13.1 A at ΔT = 40 K per IEC 62024-2-2020. Saturation current is 4 A typical at 10% inductance drop and 9.5 A typical at 30% drop. DC resistance is 9.1 mΩ ±10% at 20°C, and self-resonant frequency is 12 MHz typical.

 

This inductor features a shielded construction to minimize electromagnetic interference, with a 1365 package size (13.0 mm x 12.8 mm x 6.5 mm). It is designed for operating temperatures from -40°C to +155°C, making it suitable for automotive and industrial environments. The component is AEC-Q200 rated and is RoHS3 and REACH compliant with MSL 1.

 

Typical applications include DC-DC converters, power supplies, and high current filtering in automotive, industrial, and consumer electronics where compact size and high efficiency are required.
