744873100 Description

Short technical summary and product information.

The 744873100 is a shielded coupled inductor from Würth Elektronik's WE-DD series. It features two coils each with 10µH inductance (20% tolerance) and a 1:1 turns ratio. The component is rated for 4.2A per winding (ΔT=40K) with a typical saturation current of 7.5A. DC resistance is 0.031Ω typical and 0.042Ω maximum per winding. The self-resonant frequency is 20MHz typical, and the maximum operating voltage is 80V DC. The inductor is shielded and surface mountable in a nonstandard package measuring 12.5mm x 12.5mm x 8.5mm. Operating temperature range is -40°C to +125°C. It is RoHS, REACH, and halogen-free compliant with MSL level 1. This coupled inductor is designed for use in DC-DC converters, power supplies, and signal isolation applications where compact size and high current handling are required.
