Product role
The K4000004 is part of the K4000001–K4000004 matching-transformer family. In an ultrasonic drive circuit, the transformer can help transform voltage and impedance so electrical energy is transferred effectively to the piezoelectric load.
What to evaluate
- Target transducer and operating frequency
- Primary and secondary inductance
- Turns ratio and source voltage
- Waveform, burst length, repetition rate, and duty cycle
- Expected load and tuning components
- Board layout, mounting, temperature, and insulation requirements
The correct transformer should be selected with the complete transducer and drive circuit. Request the current controlled drawing and electrical specification.
