Mica and PTFE Capacitors

Mica and PTFE capacitors are widely used in different kinds of electronics applications. They can provide a great performance at high temperatures, making them ideal for applications like medical, aerospace, industrial, military, automotive and many other applications. The MCH38FM470J application field and working principle is a combination of mica and PTFE to provide excellent performance in high temperature applications. Mica is a natural mineral, consisting of sheets of silicate and small amounts of mica crystals. Mica is low dielectric constant material, which increases the capacitance of the capacitor. The mica also adds a high resistance to moisture, making the capacitor more reliable in high temperature and humid environments. PTFE, also known as polytetrafluoroethylene is a synthetic material made of fluorine molecules arranged in a three-dimensional network. This network allows for the material to be highly elastic and has excellent electrical properties, making it ideal for capacitors. PTFE also has good self-healing properties, meaning that any damage caused to the dielectric layer will be repaired over time. It also provides exceptional dielectric strength and high insulation resistance. The combination of these two materials makes the MCH38FM470J ideal for high temperature, high quality capacitors. The capacitor is able to withstand temperatures up to 150° C and provides an especially low dissipation factor, ensuring that the capacitor can handle a high ripple current with high peak currents. This makes it ideal for applications such as power supplies and electric vehicles. The MCH38FM470J also features a single, polarized aluminium electrolyte for improved reliability. The capacitor is able to maintain a high capacitance over a wide range of working temperatures. It also has an extremely low ESR (equivalent series resistance) making it ideal for high frequency applications. Overall, the combination of mica and PTFE in the MCH38FM470J provide applications with a high-quality, reliable, and high temperature capacitor. It is able to withstand temperatures up to 150°C and provides excellent high peak current and ripple current performance.
