7443310100 Description

Short technical summary and product information.

The Würth Elektronik 7443310100 is a WE-HCC series SMT high current cube inductor, featuring a shielded drum-core wirewound construction with an iron powder core. It provides a nominal inductance of 1µH measured at 100kHz and 10mA, with a tolerance of ±20%. The component is designed for demanding power applications requiring high current capability and low losses.

 

Electrically, the inductor delivers a performance rated current of 32.5A maximum at a temperature rise of 40K (I_RP,40K), in accordance with IEC 62024-2-2020 Class D test conditions. Its saturation current is typically 28.5A at a 10% inductance drop and 55.1A at a 30% drop. The DC resistance is 1.95mΩ typical and 2.5mΩ maximum at 20°C, while the self-resonant frequency is typically 100MHz. Maximum operating voltage is 120V.

 

The device operates over a temperature range of -40°C to +125°C, with ambient temperature limited to +75°C when running at rated current. Its shielded design minimizes electromagnetic interference, making it suitable for high-density power boards. The component is qualified to AEC-Q200 Grade 1, supporting automotive and industrial applications.

 

The inductor is supplied in a nonstandard SMD package measuring 12.1mm (length) × 11.4mm (width) × 10.0mm (height). It is RoHS3, REACH, and halogen-free compliant, and has MSL 1 classification for moisture sensitivity.
