Miniaturized series of gate-drive transformers switch within a range of 150 kHz to several MHz
The size reduction of the transformers results in significant space savings on circuit boards. Thanks to a special winding technology, parasitic capacitances between windings are only 25 to 95 pF, depending on the type. Stray inductances are likewise low. They range between 0.9 and 2.5 µH. Short-term dielectric strength is tested to 1500 V DC for all types of the B82804A series. These components are designed for ambient temperatures of up to 85 °C and operating temperatures of up to 125 °C. Their terminal configuration and pin assignment correspond to the industry standard. The main applications of these new transformers are half- and full-bridge converters as well as in frequency converters or inverters.
