WE-UNIT Off-Line Transformers

Würth Elektronik Midcom WE-UNIT Off-Line Transformers are designed for use in AC/DC switch-mode power supplies. These transformers work with a wide input voltage range from 125VDC to 375VDC with an isolation voltage of 4kV. The UNIT series uses the standard bobbins and core sizes EE13 and EE16, which guarantees short lead times. Both the EE13 and EE16 sizes are offered in a vertical and horizontal layout. Typical applications for Würth Elektronik Midcom WE-UNIT Off-Line Transformers include tiny switch ICs and SMPS with universal input from 85VAC to 265VAC.
