Mica and PTFE Capacitors

Mica and PTFE capacitors, also known as mica or PTFE capacitors, are components that are used in both commercial and industrial applications to store electrical energy for use in a wide variety of applications. Generally speaking, they are made up of two premium components, namely mica and PTFE. Mica is a mineral that is generally found in natural forms, while PTFE is a plastic or a fluorocarbon material that is made from the combination of elements like carbon and fluorine. This combination of two components makes them unique in their capacity to store electrical energy. The electrostatic properties of mica and PTFE provide the capacitors with very high insulation resistance that is very beneficial for their application in a wide range of electrical and electronic devices.

D105F331JO3 Application Field and Working Principle

The D105F331JO3 from Fujitsu Components America, Inc. is a mica-PTFE capacitor specifically designed for signal and power line filtering, high voltage power line noise suppression, and other commercial and industrial applications. The capacitor is constructed with mica as the dielectric material providing superior long-term stability and reliability. It is available in voltages ranging from 0.33 µF to 33 µF, and is rated at a maximum operating voltage of 500V. The D105F331JO3 has excellent self-healing properties and is capable of withstanding high surge voltage of up to 10 times the rated voltage.

The working principle of the D105F331JO3 is fairly simple. The capacitor stores electrical charge on the two electrically charged plates in the capacitor, creating a static electric field. When the capacitor is connected in series with an AC supply, the electric field varies with the input voltage, causing a current to flow through the capacitor. This current charges the capacitor and, as a result, energy is stored in the capacitor. The amount of energy stored in the capacitor depends on the size of the capacitor, the voltage, and the frequency of the supply.

The capacitor is generally connected in series with the input power line and, depending on the application, it can be used to filter the power line of high frequency noise or reduce the size of voltage spikes on the power line. The capacitor helps to limit the peak current that a device can draw from the power line and maintain the power line within the required voltage range, while also providing protection against over-voltage, under-voltage, or short-circuits.
