744778133 Description

Short technical summary and product information.

The Würth Elektronik 744778133 is a WE-PD series SMT shielded power inductor with a drum core, wirewound construction and ferrite core material. It offers an inductance of 33µH with ±20% tolerance. The component is rated for a maximum DC current of 1.22A (ΔT=40K) and a performance rated current of 1.85A per IEC 62024-2-2020 Class C. Saturation current is 1.15A typical at 10% inductance drop and 1.45A typical at 30% drop. DC resistance is 153mΩ typical and 240mΩ maximum at 20°C. Self-resonant frequency is 16MHz typical. Maximum operating voltage is 120V.

 

The inductor is housed in a nonstandard 7332 package measuring 7.30mm x 7.30mm x 3.40mm. It is fully shielded for EMI reduction. Operating temperature range is -40°C to +125°C, with ambient temperature range for rated current from -40°C to +85°C. The component is AEC-Q200 Grade 1 qualified, RoHS compliant, REACH conform, halogen free (JEDEC JS709B), and has MSL 1 (unlimited).
