Tester for surface sticking capacitor

The utility model relates to a tester for a surface sticking a capacitor. A large-sized device is adopted to test the traditional surface sticking the capacitor; if the large-sized device is used for testing the simple discrete components, the large-sized device wastes the talent of the large-sized device on the test of the simple discrete components, and the cost of the large-sized device is high. The utility model provides a tester for a surface sticking a capacitor, comprising a RC oscillating circuit that comprises a resistor and a 555 gate circuit. Wherein, the capacitance that is ready for being measured forms a capacitor in the RC oscillating circuit. The tester for the surface sticking the capacitor also comprises an impulse counter that is adjacent to the RC oscillating circuit and is counted the oscillating impulse generated by the RC oscillating circuit, a fiducial value memorizer that is stored the fiducial value of the capacitor that is ready for being measured, and a comparator that is connected with the impulse counter and the fiducial value memorizer, is compared the count values of the impulse counter and the fiducial values of the fiducial value memorizer, and is output the comparative result.
