Capacitor of interpose of paper of 8 oily dip: It is a paper interpose capacitance dip is in the oil that passes special processing, can enhance its compression. Its characteristic is capacitance big, compression is tall, but volume is larger. In addition, in applying actually, the first use that wants a basis to differ chooses the capacitor of different type; The 2nd what should consider capacitor is nominal capacity, allow the technical parameter such as resistor of value of error, compression, leakage of electricity; The 3rd to having, of negative pole sex electroanalysis for capacitor, , negative pole is not received when solder instead.
