744031004 Description

Short technical summary and product information.

The 744031004 is a surface mount shielded power inductor from Würth Elektronik's WE-TPC series. It features a drum core, wirewound construction with ferrite core material. The inductor offers an inductance of 4.7µH with ±30% tolerance, tested at 100 kHz/100 mV. It has a rated current of 1.2A (ΔT=30K) and a saturation current of 0.9A typical. The DC resistance is 90mΩ typical and 105mΩ maximum. The self-resonant frequency is 75 MHz typical. The component is shielded to reduce electromagnetic interference. Operating temperature range is -40°C to +125°C. The component is RoHS, REACH, and Halogen Free compliant. It is supplied in a nonstandard 3816 package (3.8mm x 3.8mm x 1.8mm) with MSL level 1. Designed for general electronic equipment, this inductor is suitable for power supply circuits and DC-DC converters where compact size and low profile are required.
