The 78250MC is a 300mA low-profile surface mount Converter Transformer with matte tin finish industry standard pin-outs and toroidal-style construction. This 78250 series transformer is fully encapsulated and rated with 2mH primary inductance and 1500Vrms isolation voltage. The materials used for this transformer are mates with UL94V-0 standards. This converter transformer is specifically designed for use with Maxim chipsets to provide isolated RS232 interfaces. Carefully controlled turns ratios ensure consistent performance whilst a toroidal construction minimizes EMI.
