744873101 Description

Short technical summary and product information.

The Würth Elektronik 744873101 is a shielded surface-mount coupled inductor from the WE-DD series. It contains two 100 µH coils with a 1:1 turns ratio, designed for general electronic equipment. The component meets RoHS, REACH, and halogen-free requirements.

 

Electrical specifications include a rated current of 1.38 A per coil at a 40 K temperature rise, a saturation current of 2.2 A typical, and a DC resistance of 0.235 Ω typical per coil. The self-resonant frequency is 4.4 MHz, and the maximum operating voltage is 80 V DC. The operating temperature range is -40°C to +125°C.

 

The inductor uses a nonstandard surface-mount package measuring 12.5 mm by 12.5 mm with an 8.5 mm height. It is shielded to reduce electromagnetic interference and has a moisture sensitivity level of 1. Storage conditions are below 40°C and 75% RH in original packaging.
