Based on the material properties of capacitors: aluminum electrolytic capacitor, film capacitor, Tantalum capacitor, ceramic capacitor, super capacitor.

Dingfeng capacitors are professional manufacturers of various film capacitors and electrolytic capacitors. Comparative advantages of electrolytic capacitors and film capacitors.

The current is greater than the allowable steady-state current, the operating voltage exceeds the operating voltage, the reverse voltage, and the frequent charge and discharge. But the most direct reason is the high temperature.

To be sure, ESR is one of the main parameters for measuring a capacitor's characteristics. However, if you choose a capacitor, you should avoid the ESR as low as better, and the higher the quality, the better. To measure a product, we must consider it in all directions and from multiple angles. We must not exaggerate the role of capacitors intentionally or unintentionally.

Film capacitors can be divided into DC film capacitors and AC film capacitors. A DC film capacitor is a film capacitor that operates in a circuit that is powered by a DC power source.The AC film capacitor refers to a film capacitor that operates in a circuit that is powered by an AC power source.

How can it be judged that the capacitor is broken? 1, using a digital capacitance meter to measure. 2, using the pointer multimeter measurement. 3, short circuit connection.

Film capacitors have many advantages and has a great advantage in price, so the proportion of market occupancy is very high. DINGFENG capacitors are professional manufacturers of various types of film capacitors, can provide you with the cheapest wholesale price.

The working principle of the capacitor is that the electric charge will move under the electric field. When there is a medium between the conductors, the electric charge is hindered to cause the electric charge to accumulate on the conductor, resulting in the accumulation of electric charge.

The starting capacitor is an AC electrolytic capacitor, a polypropylene or polyester capacitor, used to start a single-phase asynchronous motor.A single-phase motor with too small a starting capacitor can cause difficulty in starting. If the capacitor is too large, it will burn out the motor, so it is important to choose a suitable capacitor.

The annual sales volume of Dingfeng capacitors is increasing every year. By the end of August, sales in 2018 have reached more than 50 million yuan. The number of capacitors sold is more than 6 million. Although it was a low season for sales in August, the sales of Dingfeng capacitors also reached more than 6 million yuan.

Power capacitor failure, power factor can not reach the reasons and solutions:1. If the capacitor is used for a long time, it will cause the capacitance to decay. 2, the harmonic content of the power grid exceeds the standard, resulting in damage to the power capacitor. 3, the selection of power capacitors is low.

6 points of attention when storing and using aluminum electrolytic capacitors.During operation of the aluminum electrolytic capacitor, the voltage applied to the terminal of the capacitor must not exceed the rated working voltage.aluminum electrolytic capacitors must be used within the allowable range of operating temperature.

Film capacitors need attention when selecting models:1. Pay attention to the wiring method when selecting the film capacitor.2. Pay attention to the rated voltage when selecting the film capacitor.3. Pay attention to the rated current when selecting the film capacitor. 4. Pay attention to the temperature coefficient when selecting a film capacitor.

In order to prevent a capacitor from igniting, check it frequently:
1. Whether the various protection devices are complete and the protection characteristics match.
2. Detect the ambient temperature.
3. Test if the capacitor is overheated.

Capacitors have five important characteristic parameters to understand: nominal capacitance, allowable deviation, rated voltage, insulation resistance, and loss.

During the use of electrolytic capacitors, its service life is a matter of great concern to us. Voltage, current, switching frequency, installation form, and heat dissipation method are all factors that affect the life of electrolytic capacitors. Therefore, in actual use, we need to optimize these factors as much as possible.

CBB61 is a polypropylene capacitor, which is a starting and running capacitor for single-phase motors commonly used in AC mains power supply. We call this the starting capacitor. In electric water pumps, various AC fans, AC exhaust fans, and even in motors such as washing machines and refrigerators.

Note on the use of metallized film capacitors:
1. Working voltage.
2. Working current.
3. Capacitor charging and discharging.
4. Flame retardancy.
5. Ambient temperature.

CBB is a polypropylene film capacitor with the following advantages:
1, the loss is extremely low;
2. The medium absorption coefficient is low;
3. High insulation resistance;
4, the frequency characteristics are good;
5. Excellent self-healing and high stability.

1. Electrolytic capacitors have positive and negative polarity, so they cannot be reversed when used in a circuit.
2. The voltage applied across the electrolytic capacitor must not exceed its allowable operating voltage.

The nominal letters of the English letters of different dielectric capacitors are different. In order to facilitate the correct identification of capacitor products and maintenance, the following is a list of capacitors.

Aluminum electrolytic capacitors have always been a common choice for power supplies. However, they have a limited life span and are susceptible to extreme conditions of high temperatures and low temperatures.

(1) Capacitors can store charge and have the function of blocking DC
(2) AC can “pass” capacitors
(3) Capacitive reactance of capacitor

Aluminum electrolytic capacitors are the main components used in almost all electrical equipment. Leakage resistance is one of many electrical features that a capacitor is tested. Leakage is generally expressed as a leakage current at a particular voltage (usually the operating voltage).

The film capacitor is formed by winding two plastic films with metal electrodes into a cylindrical shape and finally molding. Since the medium is usually a plastic material, it is also called a plastic film capacitor. ...

Generally, the capacitance of a single-phase motor is designed according to the power of the motor. For example, a 1 kW dual value motor starting capacitor is between 100 and 200 uf, and the running capacitor is about 30 uf.
How to calculate the starting capacitor and running capacitor of single-phase motor?
Running capacitor capacity: C=120000*I/2.4*f*U*cosφ
...

The capacitor withstand voltage is the rated operating voltage of the capacitor. This voltage value cannot be exceeded in the circuit, otherwise the capacitor may be in danger of breakdown or even explosion. When selecting a capacitor, it is generally appropriate to make the rated working voltage 1.5 to 3 times larger than the actual working voltage.

Some household appliances used in our daily life, such as air conditioners, refrigerators, washing machines, electric fans, etc., are widely used in single-phase asynchronous motors, which use start-up capacitors.
Single phase means that there is only one 220V live wire and one neutral wire. Ordinary household appliances are single-phase power supply...

Air conditioning is one of the essential household appliances. Capacitors are very important components of air conditioning. If the capacitor is damaged, the air conditioner will not work properly.
The method of checking whether the capacitor is damaged can be measured with the ohmmeter of the pointer multimeter. If the deflection of the pointer is large, it means the capacitor is damaged. It is necessary to replace the capacitor of the air conditioner in time.
...

The main reason for the capacitor being damaged due to malfunction is that:
1. The internal components of the capacitor break down due to poor manufacturing quality and the like.
2. Insulation due to poor casing sealing and reduced insulation resistance.
3. Due to oil leakage, oil leakage, oil surface drop, resulting in discharge or component breakdown of the outer casing.
