Description

General part information

78253 Series

The 78253/55MVC is a 200mA low-profile through hole Converter Transformer with matte tin finish industry standard pin-outs and toroidal-style construction. This 78253 series transformer is fully encapsulated and rated with 240mH primary inductance and 4000VDC isolation voltage. The materials used for this transformer are mates with UL94V-0 standards. This converter transformer is specifically designed for use with the MAX253 chip set to provide isolated power supplies. The 5Vversion can supply 1W and the 3.3V version can supply 500mW. A centre tapped secondary winding allows for full bridge, half bridge or voltage doubling.
