GDHY CBB81 223j2kv capacitor high voltage metallized polypropylene film capacitor cbb capacitor replacement

With the development of technology level, the replacement cycle of electronics, household appliances, communications and other industries is getting shorter and shorter, and the film capacitor with its good electrical performance and high reliability, has become an indispensable electronic component to promote the replacement of the above industries. CBB81 223j2kv capacitors are widely used in filter, noise suppression and low pulse circuits. CBB81 223j2kv capacitor CBB capacitor replacement specially designed for horizontal resonance circuit of colour TV. 

The usual film capacitor is made of aluminum foil as electrode and plastic film after overlapping and winding together. But there is another way of making film capacitors, called Metallized Film, which is made by vacuum steaming a thin layer of metal on a plastic film as an electrode. In this way, the thickness of electrode foil can be saved and the volume of capacitor per unit capacity can be reduced. Therefore, the film capacitor is easier to be made into a small capacitor with large capacity.

Film capacitor is known as Self Healing Action. It is assumed that when a small part of the electrode is short-circuited due to a weak boundary, the electrode metal around the short-circuited part will be affected by the electrostatic energy or short-circuited current in the capacitor at that time. And cause a larger area of melting and evaporation to restores the insulation, so that the capacitor restore the function of a capacitor again. CBB81 223j2kv capacitor CBB capacitor replacement specially designed for horizontal resonance circuit of colour TV.

Film capacitors main characteristics are as follows: no polarity, high insulation impedance, wide frequency response, and very little dielectric loss. Based on the above advantages, film capacitors are widely used in analog circuits. Especially in the part of signal cross-connection, it is necessary to use a capacitor with good frequency characteristics and very low dielectric loss to ensure that the signal will not have too much distortion during transmission.
