TDK Corporation (TSE:6762) presents the new B78302A* series of compact EPCOS transformers with innovative E5 cores for ultrasonic applications. It comprises three types with transformation ratios between 1:1:10.8 and 1:1:15.3. Depending on the type, the new transformers in SMD design offer inductance values between 2 mH and 4 mH and are suitable for frequencies from 50 kHz to 300 kHz. The AEC-Q200 qualified components have very compact dimensions of only 8.1 x 7.0 x 7.0 mm and are shielded by a counter-winding for better interference suppression. The permissible temperature range is between -40 °C and +125 °C.

TDK Corporation (TSE:6762) presents the EPCOS E13EMHV series of compact SMT transformers with high dielectric strength for a wide range of DC-DC converter topologies. The isolation distances comply with IEC 60664-1, 61558-2-16 standard, achieving a high working voltage of 1000 V DC. Transient overvoltages of up to 2500 Vpeak are permitted. The high dielectric strength between the primary and secondary sides is 3000 V AC (50 Hz, 60 seconds).

TDK Corporation (TSE:6762) presents the new B78416A* series of compact EPCOS transformers with EP 6 cores for ultrasonic applications. The series comprises five types with transformation ratios between 1:1:8.42 and 1:1:15. Depending on the type, the new SMD-version transformers offer inductance values between 3 mH and 5 mH and are suitable for frequencies between 52 kHz and 300 kHz. The components are compliant with AEC-Q200, feature highly compact dimensions of just 9.0 x 7.6 x 7.1 mm and are magnetically shielded for better interference suppression. The permissible temperature range lies between -40 °C and +125 °C.

TDK Corporation (TSE: 6762) presents the EPCOS E10 EM series, a new range of insulated SMT transformers that are suitable for various DC/DC converter topologies and gate driver circuits in e-mobility and industrial electronics. There are four models in the series, with basic winding insulation of a working voltage of 500 VRMS and reinforced insulation of 300 VRMS. The turns ratio is between 1:0.76 and 4:1, depending on the model.
