What are the characteristics of the CL capacitance of thin film capacitors

Advances in science and technology have promoted the development of the electronic industry, in which capacitors are an indispensable type of electronic components. A capacitor is a container that holds and stores charges and has a capacitor inside an electronic product. Capacitors are mainly used in the circuit of direct connection, coupling, bypass, filter, tuning circuit, energy conversion, control and other aspects, with the emergence of electronic products, the development of the capacitor industry is also better.

There are many kinds of capacitors. The familiar capacitors in life are regular capacitance, thin film capacitance, super capacitance and ceramic capacitance. There are many kinds of film capacitance, which can be divided into polyethyl ester capacitance, polypropylene capacitance, polystyrene capacitance and polycarbonate capacitance according to the capacitance of the dielectric material film. Thin-film capacitors are divided into T-type thin-film capacitors, P-type thin-film capacitors and N-type thin-film capacitors according to the dielectric.

CBB film capacitance is widely used in film capacitance. CL capacitance is also a film capacitance which is often used. CL capacitance is often called polyester or polyester film capacitance. It is made of polyester film as media, metal foil as electrodes, inductive or non-inductive winding into a cylindrical structure, and is encapsulated with flame retardant epoxy resin outside.

CL capacitance uses polyester membrane material as the medium, so it has the advantages of high dielectric constant, large capacity, small size and good stability, which is suitable for the bypass capacitance in the circuit. In addition, the advantages of CL capacitor such as small dielectric loss and excellent bypass characteristics are widely used in analog circuits, especially in the signal cross-linking part, good frequency characteristics must be used. Capacitors with low dielectric loss, such as CL capacitor, ensure that the distortion when transmitting signals is not too large.

CL capacitors are sold by many bad merchants because of their good characteristics and usage. People should pay attention to distinguishing when choosing CL capacitors.
