Mica and PTFE capacitors consist of a low-loss capacitor dielectric which is sealed between two electrodes. The electrodes can be constructed of mica, ceramic, PTFE, or other non-polar materials. The most common combination is mica and PTFE. The combination of these two materials produces a capacitor with very low electrical loss, high stability, and excellent heat dissipation characteristics. The MCM01-009EF111J-F is a very popular type of mica and PTFE capacitor.

Application Field

Mica and PTFE capacitors are suitable for use in high-frequency, high-voltage applications such as high-frequency RF filters, high-voltage pulse generators, and pulse capacitors for transmitter amplifiers. The MCM01-009EF111J-F is an ideal choice for these applications due to its low electrical losses and excellent heat dissipation characteristics. It is also suitable for use in precision high-frequency circuits, high-power semiconductor devices, and other high-voltage pulse circuits due to its low overall inductance.

Working Principle

A mica and PTFE capacitor operates on the principles of capacitance and dielectric absorption. When an alternating voltage is applied across the capacitor plates, an electric field is generated across the dielectric material, resulting in a charge separation. This charge separation causes a current to flow through the capacitor, resulting in capacitive reactance. The dielectric material also absorbs some of the electrical energy from the electric field, resulting in a slightly lower voltage across the capacitor. This phenomenon is known as dielectric absorption.

The MCM01-009EF111J-F utilizes a high-purity mica/PTFE layer as its dielectric material. This dielectric layer provides low leakage, low dielectric absorption, low inductance, and low insertion loss. This combination of characteristics makes the MCM01-009EF111J-F an ideal choice for high-frequency, high-voltage applications. For this reason, it is widely used in RF filters, high-voltage pulse generators, transmitter amplifiers, and many other applications.

The construction of the MCM01-009EF111J-F also includes multiple layers of conductive material. This material is patterned in such a way as to ensure that the inductance of the capacitor is minimized. The combination of low leakage, low dielectric absorption, and low inductance makes the MCM01-009EF111J-F the ideal choice for high-frequency, high-voltage applications. In addition, due to its excellent heat dissipation characteristics, it is also suitable for use in precision RF circuits and high-power semiconductor devices.
