Mica and PTFE Capacitors

CMR07F822JPDM, a product of AVX Corporation, is a mica and PTFE capacitor. It is a non-polarized radial type capacitor which has temperature coefficient of capacitance (TCC) of approximately 125 ppm/ºC and temperature range of -55 ºC to +125 ºC. CMR07F822JPDM has stable electrical performance under a wide range of temperatures and superior resistance to radiation. Its elevated temperature resistance is particularly suited for high temperature environments and applications such as aerospace and industrial use.

The material of CMR07F822JPDM consists of two layers of top quality mica plates, which are respectively treated on both sides with PTFE. These two layers are bound together with epoxy resin adhesive and stacked on a non-conductive core. The core is then coated with silver center electrode and black epoxy resin. By placing a shield over the unit, the capacitor can be wrapped and molded into a single compact unit. The composition of the materials used to make CMR07F822JPDM makes it more immune to electrical stresses and other environmental conditions such as moisture, heat, shock and vibration.

The working principle of CMR07F822JPDM is twofold. Legally speaking, it is a non-polar capacitor. This means that it does not "select" one polarity over another the way a regular capacitor does. Instead, the plate electrodes are designed to function equally when connected to either the positive or the negative voltage source. Technically speaking, CMR07F822JPDM works by using two dielectric materials, mica and PTFE. The mica material serves as a dielectric medium, allowing electric charges to freely pass between the two electrodes. The PTFE coating functions as a dielectric covering, reducing losses or high current spikes, as well as providing protection against moisture and other environmental conditions.

CMR07F822JPDM offers numerous advantages when used in different applications. Its radiation resistance makes it highly suitable for use in satellites, and its elevated temperature range allows it to be used in various high-temperature environments. The capacitor\'s non-polarity also makes it ideal for applications such as motors, where two polarities are both used. Overall, the combination of mica and PTFE makes the CMR07F822JPDM an ideal capacitor choice for a wide range of applications.
