From TDK Corporation comes the 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 and 5mH. They are suitable for frequencies between 52 and 300kHz.
These AEC-Q200-compliant components feature highly compact dimensions of just 9.0 × 7.6 × 7.1mm 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. They are typically applied in parking aids, industrial robots, drones, logistics robots, automated guided vehicles, and systems for fill level measurement.
