The 744771139 is a shielded power inductor from Würth Elektronik's WE-PD series. It features a drum core, wirewound construction with ferrite core material, and is surface-mount packaged in a nonstandard case measuring 12.00mm x 12.00mm with a maximum height of 6.00mm.
Electrically, the inductor offers 39µH inductance at 100kHz/250mV with ±20% tolerance. The DC resistance is 68mΩ max at 20°C. It has a rated current of 2.5A max (ΔT=40K) and a performance rated current of 4.3A max (per IEC 62024-2-2020, Class C). Saturation current is 2.7A typ at 10% inductance drop and 3.5A typ at 30% drop. The self-resonant frequency is 10MHz typ, and maximum operating voltage is 120V DC.
This component is qualified to AEC-Q200 Grade 1, making it suitable for automotive applications. It is RoHS3, REACH, and Halogen Free compliant, with MSL 1 (unlimited). The operating temperature range is -40°C to +125°C. The inductor is designed for power supply and filtering applications in demanding environments.
