The Würth Elektronik 7447789139 is a robust, shielded SMD power inductor from the WE-PD series. It features a drum core, wirewound construction with a ferrite core material, providing an inductance of 39µH with a ±20% tolerance. The component is designed for surface mount assembly in a nonstandard package measuring 7.3mm by 7.3mm with a height of 3.2mm.
Electrically, this inductor offers a maximum DC resistance of 320mOhm (209mOhm typical) and a rated current of 1.03A based on a 40K temperature rise. It also provides a performance rated current of 1.6A per IEC 62024-2-2020 Class C. The saturation current is 1.1A typical for a 10% inductance drop and 1.4A typical for a 30% drop. The self-resonant frequency is 14MHz typical, and the maximum operating voltage is 120V.
This component is qualified to AEC-Q200 Grade 1, making it suitable for automotive and other high-reliability applications. It operates over a temperature range of -40°C to +125°C and is compliant with RoHS, REACH, and Halogen-Free standards, with an MSL rating of Level 1.
