The electronic rodent repeller circuit is composed of the power circuit, oscillator and piezoelectric buzzer HA, and the circuit is shown as the chart. Power circuit is composed of the power switch S, power transformer T, rectifier diodes VD1 ~ VD4 and filter capacitor C5 and so on. The oscillator is composed of time-base integrated circuit IC, resistors R1 ~ R3 and capacitors C1 ~ C3 and other components. R1 ~ R3 use 1/4W or 1/8W carbon film resistors. C1 chooses high-frequency ceramic capacitor; C2 and C5 select aluminium electrolytic capacitors with the voltage in 16V; C3 and C4 use polyester capacitors or monolithic capacitors. VD1 ~ VD4 select 1 N4007 or 1N4001 silicon rectifier diodes. IC uses NE555 time-base integrated circuit. S uses a small button self-locking switch. HA uses piezoelectric buzzer.
