The following points should be noted when making power supply with capacitor voltage reduction:（1）Capacitor voltage is better above 630V, and apply non-polar capacitors, polarity capacitors can not be used.（2）Shunt the discharge resistance of the 500K-1M at both ends of the capacitor.（3）In the proce

In common low-voltage power supply, the power supply with capacitor is smaller, economical, reliable and efficient compared with transformer. The disadvantage is that it is not as safe as transformer. If AC is introduced into the load by capacitors, there is 220V voltage on the ground, and people ar

The control of the effect of heat seal on the breakdown of capacitor:The heat size of the heat seal and the length of contact between the heat seal and the core should be adjusted to the benefit of the aluminum foil. In addition, the length of the outer film should be moderate, too long wave waste r

Control of the effect of lead spot Welding on Capacitor Breakdown: 1. Establish the control document of the lead welding process in winding process, and clarify the welding status requirements of the lead and aluminum foil. For the welding quality of the capacitor core group, the operator must check

There are many uses of capacitors, mainly as follows:1. D. C: the function is to prevent the DC from passing through and to allow the AC to pass.2. Bypass (decoupling): provides a low impedance path for some shunt components in an AC circuit.3. Coupling: as a connection between two circuits, AC si

The basic electrical properties of capacitors 1.the capacitance: Capacitor capacitor charge stored on the board's ability. Taking a parallel plate capacitor as an example: C = ε.S / 4πd where C is μF, S is the area of the electrode in cm, d is the thickness of the medium in cm, and ε is the diel
