TDK-EPC EPCOS EP5 SMT pulse transformer range

TDK-EPC, a group company of TDK, has developed a series of EPCOS EP5 SMT pulse transformers, used to couple gate-drive circuits to MOSFETs and IGBTs operating at switching frequencies within a range of 150 kHz to several MHz.

These devices are available with a wide range of turns ratios, polarities and outputs.

Using miniaturised EP5 cores, they have dimensions of 8.1 x 6.7 x 5.4 mm³ and special winding reduces parasitic capacitances between windings to only 25-95 pF, depending on the type. Stray inductances are low. The transformers range between 0.9 and 2.5 µH. Short-term dielectric strength is tested to 1500 VDC 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.
