lelon aluminum electrolytic capacitors, electrolytic capacitors, green Quan Electronic

Qing Quan electronic application of aluminum electrolytic capacitors are usually polarized electrolytic capacitors in the power circuit from the power supply filtering or intermediate frequency, low frequency circuits, decoupling, and the time constant signal coupling, DC blocking and so on. Generally can not be used for AC power circuit, when used as a filter capacitor DC power circuit, which anode (positive) should be connected to the positive terminal of the power supply voltage, and a cathode (negative electrode) and the negative terminal of the power supply voltage is connected, can not be reversed Doing so can damage the capacitor. Promise of electrolytic capacitor is typically used speaker crossover circuit television S correction circuit and single-phase motor starting circuit. Electrolytic capacitors are widely used in household appliances and a variety of electronic products, its large capacity range, usually 1 ~ 1000μF, rated operating voltage range of 6.3 ~ 450V. The disadvantage is that the dielectric loss, the capacity of error is larger (maximum permissible deviation of +100% - 20%), poor heat resistance, long storage time likely to fail. Polar electrolytic capacitors, electrolytic capacitor to observe in the side "-" is negative, if not marked on the electrolytic capacitor positive and negative, can also be based on the length of the pin to determine its long foot is positive, short legs negative. One of the roles for everyone to talk about green Quan electronic capacitors - bypass bypass capacitor to provide energy for the local device energy storage device, which enables the regulator's output uniformity, reduce the load demand. Like small rechargeable batteries, the bypass capacitor can be charged to the discharge device. To minimize impedance bypass capacitors as close as possible to the load device power supply pins and ground pins. This can very well prevent ground elevation and excessive noise input values ??caused. Ground potential is connected to the voltage drop at the time by the large current spikes.
