Mica and PTFE Capacitors

CD30FD272JO3 is a mica and PTFE capacitor developed by a leading capacitor manufacturer based on the requirements of the sub-industry. In recent years, due to the high requirements of the entire industry on the performance and reliability of mica capacitors, the application field of the model is also gradually becoming more and more extensive, which is favored by many customers.

Application field

CD30FD272JO3 capacitor is mainly used in the field of electronic control systems. It is suitable for circuit occasions where safety is relatively high, such as high-voltage switching power supplies, power frequency voltage converter, etc. It can also be used for double circuit or as a series connection in a multilayer circuit board, and its application scope covers industry, automotive, medical, and military use. In addition, this model is also frequently used in the field of RF communication, such as radio, radar, communication tower, etc.

Working principle

CD30FD272JO3 capacitors are mainly composed of two parts of material, namely mica and PTFE. Mica is a mineral composed of silicon, oxygen, aluminum and other elements, which has superior dielectric properties and can resist the corrosion of moisture and chemicals. PTFE is a polymer material with a high melting point, high strength and high electrical insulation. Working together, the pair of materials store electric energy in the capacitor to meet the needs of the appliance.

In operation, the capacitor is insulated from current by the two materials. Alternating current passes through the PTFE layer and continues to flow. At the same time, the alternating current is disturbed by the mica layer, reacts back and forth between the layers, and is charged and discharged in the capacitor.

The main advantages of the CD30FD272JO3 capacitor are its excellent temperature stability, overvoltage protection and large capacity. In addition, its mechanical strength and environmental adaptability are significantly improved with the combination of mica and PTFE materials. Thanks to its excellent performance, this model of capacitor is gaining its popularity in the industrial application field.
