Ceramics capacitors meet high temperature will be bad?

Everyone should understand capacitor should be used in the appropriate temperature down, otherwise easily causes the damage of capacitor, and different types of capacitors to the working temperature of heat resistance is different, the first to introduce everyone to ceramics capacitors meet high temperature damage? ShenMao detailed answer for you. Ceramics capacitor surface usually covered a layer of metal film and then through high heat sintering as electrodes of a capacitor. Ceramics capacitors according to the material and can be divided into three kinds of characteristic Y5V, Y5U and Y5P, different characteristics of the corresponding working temperature is different also. Ceramics capacitors with Y5U and Y5P characteristics, change rate of + 22% 65%. Use Y5V characteristics, change rate of + 30% 80%. - 25 ℃ ~ + 85 ℃ is the working temperature ceramics capacitors, which means ceramics capacitors can work at two extremes of temperature. Are not affected. Our view of the problem of heat resistance in capacitance specially arranged for testers to test two temperature is obtained: use ceramics capacitors in the temperature of 200 ℃, the surface has not changed, the actual may be a drop in capacity. Then we could put the ceramics capacitors used in 800 ℃, the results of the capacitor should be can't use state of the damage. So before using ceramics capacitor must understand relevant regulations regarding the use of the product, different material heat resistance is not the same. Sometimes life is short, but capacitor capacity decline situation may also be because we use caused by improper operation, and on the other hand may be the quality of the capacitance is not pass. When purchasing ceramics capacitors and capacitor so choose normal manufacturer, quality is guaranteed. Shenzhen ShenMao weiye technology co. , LTD is a company specializing in the production of manufacturing ceramics capacitors manufacturer, 13 years focus on capacitor production and research and development, with the development of look forward to working with you.
There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their electrolytic capacitor suppliers effects. However, recent studies have provided valuable insights into how the intake of may result in improved electrolytic capacitor suppliers.
Shenzhen Shen MaoXin Electronics Co., Ltd., to be the world leader in products, services and solutions that enable and transform the way consumers and businesses gather, manage, distribute and communicate information.
As consumers get more and better information regarding how to compare various products and companies, it is critical to compete on the price and value of electrolytic capacitor.
