Instructions:

1. Power Supply: Ensure the operating voltage does not exceed 5V.
2. Frequency Operation: Operate within the resonant frequency of 40kHz for optimal performance.
3. Drive Voltage Limitation: Do not apply a drive voltage higher than 20V peak-to-peak to avoid damage.
4. Temperature Considerations: The device is designed to operate between -20掳C and 85掳C. Avoid exposing it to temperatures outside this range.
5. Handling Precautions: Handle with care to prevent physical damage. Avoid dropping or applying excessive force.
6. Mounting: Secure the component properly on the PCB to ensure stable operation and prevent mechanical stress.
7. Capacitance Matching: For best performance, match external circuit capacitance closely to the internal capacitance of 1027 pF.
