CD10FD151GO3 Capacitors

Mica and PTFE Capacitors

Mica and PTFE capacitors, also known as plastic film capacitors, are type of capacitors that use mica or polytetrafluoroethylene (PTFE) as a dielectric. These capacitors come in various types depending on the application, such as an axial mica capacitor, radial mica capacitor, and polypropylene film capacitors. They are generally used in high-frequency and high-power applications due to their excellent electrical characteristics and low effective series resistance (ESR).

The CD10FD151GO3 is a radial mica capacitor that is designed for use in high frequency, high voltage, high power applications. It is an air-variable capacitor constructed with two disks of mica dielectric material connected together using an epoxy bond. The mica dielectric layer is sandwiched between two sputtered metal layers to form the terminals and provide excellent electrical contact. The capacitor is rated for a maximum voltage of 1.5kV and a maximum capacitance of 10pF. It offers excellent mechanical robustness with a UV-resistant gold-plated finish, which makes the capacitor suitable for operating in extreme weather conditions. The capacitor also features a wide temperature range, ranging from -55°C to +125°C.

Working Principle

Mica and PTFE capacitors work on the principle of a dielectric insulator placed between two different types of conductors. The conductor acts as an electrical charge storage that stores energy in the form of electrical charge when an electric field is applied. The applied electric field causes the ions in the material to move, creating an electrical potential between the conductors. This potential is known as the capacitance of the capacitor.

The dielectric material used in mica and PTFE capacitors can affect the capacitance of the device. Mica is a highly resistive material that does not allow electrons to flow through it. The insulating properties of mica make it a great choice for high-voltage applications, such as those found in transmission lines. PTFE is also an excellent dielectric material due to its high dielectric strength and low dielectric constant, which is useful in high-frequency applications.

The CD10FD151GO3 is designed to operate at high frequency and voltage levels, making mica and PTFE dielectric materials the ideal choice. Its high temperature range, robust construction, and wide voltage range make it a great choice for high-power applications such as power supplies, inverters, and converters. It is also useful in telecommunications applications such as switches and antennas due to its low ESR.
