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.

The transformers are used in ultrasonic applications for optimum impedance matching between the driver IC and the ultrasonic transmitter or receiver. Typical applications include parking aids, industrial robots, drones and logistics robots, Automated Guided Vehicles (AGV) and systems for level measurement.

Features

  • Very compact dimensions of only 8.1 x 7.0 x 7.0 mm
  • Operating frequencies from 50 kHz to 300 kHz
  • Permissible temperature range from -40 °C to +125 °C
  • Qualified according to AEC-Q200

Applications

  • Parking aids
  • Industrial robots
  • Drones and logistics robots
  • AGV
  • Level measurement systems
