, can be used in resistance-capacitance voltage reduction circuit.
It should be noted that the CBB22 capacitor used for resistance and capacitance buck is generally customized, which is slightly different from the ordinary CBB22 capacitor used for resistance and capacitance buck, which must have small capacity attenuation, otherwise the service life will be short. CBB22 can be used on LED and small home appliance control boards to replace transformers and play a role in resistance and capacitance reduction.
2, can be used for filtering circuit.
In fact, the capacitor has a filtering effect, of course, the CBB22 capacitor is also one of the important filter capacitors, the function of the filter capacitor is simply to make the output voltage after the filter is a stable DC voltage, the working principle is that the capacitor charges when the rectifier voltage is higher than the capacitor voltage, when the rectifier voltage is lower than the capacitor voltage, in the process of charging and discharging, the output voltage is basically stable. CBB22 is one of the commonly used filter capacitors, it is cheap, stable performance, used in the filter circuit is very reliable.
3, CBB22 capacitor can be used for bypass action.
The bypass capacitor is an energy storage device that provides energy to the local device, which can homogenize the output of the regulator and reduce the load demand. Just like a small rechargeable battery, the bypass capacitor can be charged and discharged to the device. In practical circuit use, the CBB22 capacitor is also often used for bypass action.
4, switching circuit coupling.
CBB22 capacitor is also often used in switching power supply, mainly play a coupling role, switching power supply as a power supply device for electronic equipment, with small size, light weight, high efficiency advantages, in the digital circuit has been widely used, but because of the work in the high-frequency switching state, belongs to the strong interference source, Its own interference directly endangers the normal work of electronic equipment. Therefore, in the switching circuit, the CBB22 capacitor is generally used to play the role of circuit coupling.
5, CBB22 can be used in resonant circuits.
CBB22 capacitors can be used in appliances requiring high frequency, high current and high stability, in DC, pulse, high frequency and large current occasions can be used, in some resonant circuits, CBB22 capacitors can also be fully resonant. It should be noted that if it is a larger high-frequency high-voltage circuit, it is necessary to use CBB81 or MMKP82 capacitors.
