74435571500

The 74435571500 is a shielded, wirewound, drum core inductor from Würth Elektronik, part of the WE-HCI series. It features a metal composite core and is designed for high current applications in general electronic equipment.

Electrical specifications include an inductance of 15 µH ±20% measured at 100 kHz/10 mA. The rated inductance is 12 µH typical at 14 A. DC resistance is 9 mΩ nominal. The rated current is 14 A maximum at a temperature rise of 50 K, and the performance rated current is 14.1 A per IEC 62024-2-2020 at 40 K. Saturation current is 10.75 A typical at 10% inductance drop and 14 A typical at 30% drop. Self-resonant frequency is 14 MHz typical.

Mechanically, the inductor is surface mount with a nonstandard package (supplier device package 1890). Dimensions are 18.3 mm length, 18.2 mm width, and 9.2 mm height. Operating temperature range is -40°C to +125°C. The component is AEC-Q200 qualified and RoHS compliant with MSL 1.

Designed for general electronic equipment, this inductor is suitable for high current power conversion and filtering applications. Temperature rise in application depends on PCB land pattern, trace size, and proximity to other components and should be verified in the final design.
