EPCOS B82804A Series Gate Drive Transformers

EPCOS B82804A Series Gate Drive Transformers

EPCOS B82804A Series Gate Drive Transformers are used to couple gate-drive circuits to MOSFETs and IGBTs operating at switch frequencies within a range of 150KHz through several MHz. Using a miniaturized EP5 core, the dimensions of the transformers are 8.1 x 6.7 x 5.4 mm, resulting in a significant space savings on the circuit board. EPCOS B82804A Series Gate Drive Transformers offer low stray inductances and parasitic capacitances between winding are only 25 to 95 pF. Short-term dielectric strength is tested to 1500 VDC for all types in the B82804A Series Gate Drive Transformers are designed for ambient temperatures of up to 85ºC and operating temperatures of up to 125ºC. Applications include half- and full-bridge converters as well as in frequency converters or inverters.
