For outsiders, the many marks on the CL21 capacitor, or some models and abbreviations are difficult to understand. After all, the types or numbers of capacitors included in the field of capacitors are too cumbersome and complicated to grasp. So what does cl21 capacitor mean? Next, we will introduce it in detail, and take you to understand the relative advantages and disadvantages and application scope.
The so-called cl21 capacitor is actually a metallized polyester film capacitor. The cl21 capacitor is a non-inductive structure, which is wound with a metalized polyester film as the point medium / electrode. The wire is tinned copper wire and sealed with epoxy resin. The medium used is polyester film, and the electrode is a metal vacuum evaporation layer. At the same time, the encapsulation form of flame-retardant epoxy resin is adopted to ensure the guarantee of its transportation quality.
The capacity range of cl21 capacitor is relatively wide, but relatively speaking, the volume is relatively small. However, its own advantages are great. It not only has good self-healing performance, but also has a long service life. Compared with ordinary capacitors, its life is more guaranteed. Relatively speaking, it is mainly suitable for DC and VHF signal bypass, bypass and coupling, filtering, noise reduction, low pulse balance circuit.
Cl21 capacitors are produced in strict accordance with GB7332 (IEC384-2) standard during the production process. Its small size is easy to install, and it also has pulse strength and high reliability. It is recommended to use CBB21 when the rated voltage is greater than 250V.
These are the advantages and disadvantages of cl21 capacitors and application introduction. On the basis of these advantages, the development of the capacitor in the industry is guaranteed. After all, there are advantages and disadvantages, and no product can be perfect.
