TDK offers compact transformers with EP 6 cores for ultrasonic applications


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.

The transformers serve optimal impedance matching between the driver IC and the ultrasonic transmitter or receiver in ultrasonic applications. Typical applications include parking aids, industrial robots, drones, logistics robots, automated guided vehicles (AGVs) and systems for fill level measurement.
