The CD42FC563JO3F is a mica and PTFE capacitor offering superior performance and reliability in a wide array of applications. This type of capacitor is designed for use in a wide variety of electronic engineering and military/aerospace systems, including radios, avionics, advanced tracking systems, and more.

Application Fields

CD42FC563JO3F capacitors are commonly used in high-frequency applications, such as in AM/FM radio and other wireless data transmission systems, cellular phones, advanced radar systems, television receivers, aircraft navigation equipment, and other avionics systems. Additionally, they can be found in sophisticated medical equipment, computers, and instrumentation.

The CD42FC563JO3F capacitor includes a thick polytetrafluoroethylene dielectric layer, topped with a thin mica layer, which works together to create a high-reliability and highly-stable capacitor. The combination of the two materials results in a capacitor with a high-frequency response, excellent dielectric strength, and a low dielectric loss.

Working Principle

The capacitance of the CD42FC563JO3F capacitor is determined by the distance between the two metal plates and the dielectric material in between them. For this particular capacitor, the two dielectric materials used are polytetrafluoroethylene and mica. The combination of these two materials provides a high-frequency, highly-stable capacitor.

When current moves through the capacitor, the electric field that is created causes the electrons to move and create a counter-electrostatic field, which opposes the original field. The counter electrostatic field increases the capacitance until it attains its maximum level. Once the maximum capacitance is reached, the electric field is cut off and the capacitor discharge begins.

The CD42FC563JO3F capacitor exhibits low dielectric losses and features high-frequency performance that is suitable for a number of applications. Additionally, the capacitor is rated for temperatures from -55°C to +125°C, which makes it suitable for applications in temperature-sensitive environments. The CD42FC563JO3F capacitor is also designed to handle high voltages of up to 600V.
