Who knows the use of BC capacitors Thank you

The predecessor of BC was Philips

BC capacitors are Philips series capacitors, and their use is the use of capacitors.

But your question is too general, according to the material of the capacitor, the characteristics, and the position in the circuit, the role can be divided into: filtering, DC-blocking, bypass, coupling, etc., and capacitors also have: tantalum capacitors, mica capacitors, aluminum electrolytic capacitors, polyester capacitors, polypropylene capacitors, ceramic capacitors, etc.

A capacitor is an energy storage element that stores the energy of an electric field

c q u transform: u q c

wherein, c: capacitance (law); Q: Electricity (Coulomb); u：

The voltage at both ends of the capacitor (volts) because the amount of charge q on the capacitor plate cannot be abruptly changed, it needs a process (charging), from which it can be seen that the voltage at both ends of the capacitor can not be abruptly changed, so for direct current, when acting on the capacitor, the voltage at both ends of the capacitor will be equal to the power supply voltage after the charging process (in fact, it can be considered that the charging process takes infinite time in theory), and the current through it will also drop to the leakage current, which can be used to block the principle of direct current. For alternating current, when acting on the capacitor, the capacitor has been in a cycle of charging and discharging repeatedly, so the capacitor always has a current flowing through, which is the principle of the capacitor through the AC.

The voltage at both ends of it can not be abruptly changed, and it can also be used for filtering, waveform formation, etc.

A capacitor is like a pool, ideally, the incoming water (electricity) is stored in the pool, and the water from the outlet will flow to where it is needed when needed. This process is continuous or intermittent, and since the outflow of water is only affected by the level of the pool and the amount of water, it can have a smooth effect on the water flowing into the gushing state, but the total amount of water does not change. Therefore, one of the most important functions of capacitors is filtering.

Other uses of capacitors: coupling, DC-blocking, energy storage.

Capacitors are mainly used for filtering.

CBB capacitors are generally used in high-frequency pulse occasions, AC occasions, high-stability timing occasions, temperature compensation circuits, switching power supply systems and color TV industries, instrumentation, televisions and household appliances, electronic rectifiers, high-voltage potential absorption circuits of various contactor contacts, as well as lighting LED circuits, filtering, bypass, coupling and other circuits.

The use of CBB capacitors is contraindicated.

Be sure to pay attention to the influence of high temperature on CBB capacitors: to confirm the temperature resistance of the purchased CBB capacitors, there are some poor quality high temperature resistance 85, *** CBB capacitors high temperature resistance 105. Secondly, be careful not to get the CBB capacitor too close to the electronic components that generate a lot of heat, and pay attention to the heat dissipation of the circuit board.

The most important parameter of CBB capacitor is withstand voltage, when the circuit voltage exceeds the rated voltage of the capacitor, the CBB capacitor may be broken down and damaged. It should be noted that when the voltage applied to the capacitor is higher than the rated operating voltage, the leakage current of the capacitor will rise, and its oxygen properties will deteriorate until it is damaged in a short period of time.

The above content refers to Encyclopedia-CBB Capacitors.

CBB capacitor: AC motor capacitor.

CBB capacitors are generally used in high-frequency pulse occasions, AC occasions, high-stability timing occasions, temperature compensation circuits, switching power supply systems and color TV industries, instrumentation, televisions and household appliances, electronic rectifiers, high-voltage potential absorption circuits of various contactor contacts, as well as lighting LED circuits, filtering, bypass, coupling and other circuits.

CBB60 is a common name in China, CBB60 capacitor is a polypropylene film capacitor, a motor running capacitor, mostly used in AC motors.

Its function is usually to maintain the operation of the motor, the plastic shell, the lead end is mostly a lead wire or metal insert.

It is common to see some capacitors marked with different letters, and the difference between any one letter is very large. The capacitor type or model represented by different letters is different. So what is a CBB60 capacitor?

CBB60 capacitors are actually polypropylene film capacitors. Polypropylene capacitors are capacitors made of metal foil as electrodes, overlapped with polypropylene film at both ends, and wound into a cylindrical structure. The principle is the same as that of polyester capacitors, with no polarity, high insulation resistance, excellent frequency characteristics (wide frequency response) and low dielectric loss.

Due to these advantages, film capacitors are widely used in analog circuits. Especially in the part of signal cross-connection, it is necessary to use capacitors with good frequency characteristics and very low dielectric loss to ensure that the signal is not too distorted during transmission. The dielectric constant is high, the volume is small, the capacity is large, the stability is relatively good, and it is suitable for bypass capacitors.

CBB60 capacitor shell: ABS, polypropylene, aluminum shell, etc., its products have good stability, impulse current resistance, strong overload capacity, low loss, high insulation resistance, long rated working life, excellent self-healing performance, built-in flame retardant epoxy resin filling safe and reliable.

The capacitor is non-toxic, non-leakage and liquid material, which is conducive to environmental protection. Mainly used in refrigerators, air conditioners, AC motors, water pumps, generators, cleaning machines, household appliances, electronic products, etc.

CBB60 capacitors have relevant technical parameters, and using them within these parameters is the key to ensure their performance and service life. CBB60 capacitors capacitance range: 3 F to 150 F; Capacity deviation:

- 5% or according to customer requirements.

And rated voltage: 125V 500VAC, 50 60Hz; Operating temperature range: -25 +70 ; Loss tangent: 50 60Hz).

CBB60 capacitors are produced and designed in strict accordance with the standards stipulated by the relevant departments. On the basis of ensuring its performance, it ensures low-cost production, and provides consumers with high-quality and low-quality products as much as possible.

CBB60 capacitors are polypropylene film capacitors and motor operation capacitors. It is mostly used in AC motors.

The function is usually to maintain the operation of the motor, the plastic shell, the lead end is mostly a lead wire or metal insert.

CBB capacitors are also known as polypropylene capacitors. Capacitance 10p--10, rated voltage: 63--2000V. It can replace most polystyrene or mica capacitors for demanding circuits. The performance is similar to that of polystyrene, but the size is small and the stability is slightly worse.

CBB capacitors, polypropylene capacitors (CBB), replace most polystyrene or mica capacitors, used in demanding circuits, and their main characteristics are similar to polystyrene but small size and slightly poor stability. It is non-polar, has a high insulation resistance, excellent frequency characteristics (wide frequency response) and low dielectric loss.

CBB capacitors function as follows:

1. Suppress the electromagnetic interference of the power supply. It can play the role of buffering in the circuit.

2. Reduce the impedance. When the film capacitor is used as a bypass, it mainly plays a role in reducing the impedance of the DC bus and absorbing the ripple from the load to dissipate the current, so as to effectively suppress the fluctuation of the DC bus voltage due to the sudden change of the load.
