how long do start capacitors last？

Capacitors, as the name suggests, are 'charged containers', a device that holds a charge. English name: capacitor. Some commonly used capacitors are shown. Expressed by the letter C. Capacitance is one of the most widely used electronic components in electronic equipment. It is widely used in isolation, coupling, bypass, filtering, tuning loop, energy conversion, control circuit, etc.

First, the working principle:

Capacitors are similar to batteries and also have two electrodes. Inside the capacitor, the two electrodes are respectively connected to two metal plates separated by a dielectric. The dielectric can be air, paper, plastic or any other material that is non-conductive and prevents the two metal poles from contacting each other.

The metal plate on the capacitor that is connected to the negative terminal of the battery will absorb the electrons generated by the battery. A metal plate on the capacitor that is connected to the positive terminal of the battery will release electrons to the battery. After charging is complete, the capacitor has the same voltage as the battery (if the battery voltage is 1.5 volts, the capacitor voltage is also 1.5 volts).

Regarding the starter capacitor, the most famous one is the CD60 startup capacitor.

CD60 starter capacitor is mainly used to high torque motor start, such as air conditioning, freezer, compressor, water pump or other single-phase supply system asynchronous motor and three-phase asynchronous motor use single phase power supply.

CD60 phenolic aldehyde resin shell start capacitor connect to PTC original. Electric relay switch and electric centrifugal switch, replace the traditional mechanical centrifugal switch.

The starting capacitor is the instant work of the appliance to start, it does not work after normal startup. So whether it is used in refrigerators, air conditioners, or refrigerators, the working time of the startup capacitor is about three years.

JINAN RETEKOOL INC is a professional manufacturer of capacitor.

We mainly produce many types of capacitors.

1. The series of CBB60,CBB65,CBB61 AC motor capacitor。    

2. CBB66 of explosion proof type capacitor for metal halide lamp

3. CBB80 of power factor compensation capacitors for tubular fluorescent lamps and other discharge lamps

4. BCMJ of shelf healing low voltage shunt capacitor

5. AKMJ and BKMJ of filter capacitor，CBG of track circuit compensation capacitor

6. DC-link of metallized polypropylene film dielectric capacitor with DC support capacitor and other special capacitor。And CD60 start capacitor。

Our products passed the CQC,UL,C-UL,CE,TUV,VDE,CSA etc.domestic and international certification,and get a lot of nation patent.

Therefore, the capacitors is a new type of environmentally friendly, efficient use of refrigeration accessorie.

The eight raw materials that make up the aluminum electrolytic capacitor are: positive foil, negative foil, electrolytic paper, guide pin (lead), rubber pellet (gel plug), aluminum shell, electrolyte, and casing. We use high quality raw materials and then guarantee the quality of our products.
