*1 : At 25 ± 3℃, 40% to 70%RH humidity.
*2 : The resonant frequency, Impedance and electromechanical coupling factor of the piezoelectric transformer will depend on the loading, input voltage, output power, and temperature.
*3 : The voltage step up ratio is dependent on the load resistance. Higher load resistance will have higher voltage step up ratio.
