Mica and PTFE Capacitors

Mica and PTFE capacitors are an important component of a wide range of electronic systems and devices. MC12FA391G-F application field and working principle is best understood by understanding the fundamentals of mica and PTFE capacitors.

What is a Mica Capacitor?

A mica capacitor is an electric component consisting of two conductive metals, separated by an insulating sheet of mica, which acts as a deposit of electricity. The most common type of mica used in capacitors is muscovite mica, which has been cut into thin, equal-sized plates and bonded together with an metal foil such as aluminum or bronze. The plates are usually 2 to 10 mils thick. These mica-based plates are then connected to a plastic or metal housing to form a complete capacitor.

What is a PTFE Capacitor?

A PTFE capacitor is an electric component consisting of two conductive electrodes, separated by a dielectric layer of polytetrafluoroethylene (PTFE). The PTFE dielectric layer typically has a thickness of 0.1 to 0.3 mils and provides an electrical insulation barrier between the conductive plates. The two plates are typically connected to a metal or plastic housing, making up a complete capacitance device.

MC12FA391G-F Application Field and Working Principle

The MC12FA391G-F is a mica-based, single-phase, instant-start capacitors that is designed to perform high-voltage and high-current switching in harsh environment. Its applications include robotic arms, motors, and pumps. The functioning of the MC12FA391G-F is based on the idea of capacitive discharge. When current passes through the capacitor, a voltage is induced across its plates to create an electric field. This electric field then induces a current flow in the wire connected to the terminals of the capacitor. The current then passes through the capacitor and is discharged through the terminals to perform the desired operation.

The MC12FA391G-F is designed with a built-in snubber circuit for reduced electrical noise and transient protection. It is also designed with low impedance and a high thermal capacity, ensuring its functionality in a wide range of operating conditions. The MC12FA391G-F is dust-proof and waterproof, making it ideal for harsh industrial environments.
