TDK B78302A series transformers for ultrasonic applications

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 2mH and 4mH and are suitable for frequencies from 50kHz to 300kHz. The AEC-Q200 qualified components have very compact dimensions of only 8.1mm x 7.0mm x 7.0mm and are shielded by a counter-winding for better interference suppression. The permissible temperature range is between -40°C and +125°C. The transformers are used in ultrasonic applications for optimum impedance matching between the driver IC and the ultrasonic transmitter or receiver.
