Mica and PTFE capacitors are well-known for their use in various applications, particularly for decoupling and snubbing circuits. The CD42FD363JP3 is a mica/PTFE capacitor manufactured by ITEC Electronics and used in decoupling, snubbing, and other high frequency applications. It is a type of surface mount capacitor with a ceramic body constructed from ceramic dielectric sandwiched between two sheets of mica and a polytetrafluoroethylene (PTFE) insulation layer. The CD42FD363JP3 is characterized by an enhanced dielectric strength, high humidity and temperature resistance, excellent high frequency characteristics, and long service life.

The CD42FD363JP3 is available as three different capacitance ratings (472, 680, and 820 nF), two different DC working voltages (630 and 1000 VDC), and two different case sizes (6.3 * 8.2 mm and 4.7 * 9.2 mm) depending on the application. The CD42FD363JP3 is suitable for a wide range of applications, including high frequency filtering, high speed switching, and RF circuits in consumer electronics. The CD42FD363JP3 is specified for a maximum operating temperature of either 250 or 500V, depending on the capacitance, and a dilatation coefficient of 4.5%.

The CD42FD363JP3 works based on the principle of electrostatic capacitance. In this type of capacitor, an electric field is established between two conductive plates that are separated by an insulating layer. The electric field causes an electrical charge to accumulate on the plates, resulting in an electric current flow. The current flow then results in an electrical field that is proportional to the capacitance of the capacitor. The properties of the plates and insulating layers dictate the capacitance and other electrical properties of the capacitor.

The capacitance of the CD42FD363JP3 is superior compared to other mica/PTFE capacitors and is well-suited for a wide range of high frequency and high voltage applications. The CD42FD363JP3 has a dissipation factor of 2%, a dielectric absorption ratio of 0.05%, a dielectric strength of 250V/mm, and an insulation resistance of 1 GΩ·μF (at 25°C). These characteristics indicate that the CD42FD363JP3 has excellent high voltage and high frequency performance.

The long service life of the CD42FD363JP3 makes it ideal for applications that require reliable operation for extended periods of time. The CD42FD363JP3 is UL94V-0 rated, indicating that it has excellent thermal resistance and low fire hazard. This makes the CD42FD363JP3 an excellent alternative to other types of capacitors in many high-grade applications. The CD42FD363JP3 is RoHS compliant, making it suitable for use in green energy applications.

In summary, the CD42FD363JP3 is a type of high performance mica/PTFE capacitor suitable for a wide range of applications.
