GDHY CL23 coupling capacitor and bypass capacitor metallized polyester film capacitor polyester capacitor

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. Coupling capacitor and bypass capacitor have good performance.                                                                                                                              

The usual metallized polyester 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 restore the insulation, so that the capacitor restore the function of a capacitor again.

Coupling capacitor and bypass capacitor polyester capacitor 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.
