Film Capacitors

Film capacitors are a type of capacitor that contains a thin film of insulation material, such as polyester, polycarbonate, polyphenylene sulfide, polypropylene, polystyrene, Teflon and other materials, as its dielectric. These film capacitors are most often used in applications such as filters, low-pass RC networks, timing, resonance, and many other circuit applications. There are a wide variety of film capacitors available, and their use depends on the needs of the application. Some of the most popular types include polyester, polypropylene, and polystyrene film capacitors.

The MKT1817210404G is a film capacitor primarily used for more general-purpose applications. This particular capacitor has a rated voltage of 200 V and a capacitance of 4 uF. This capacitor is made using metallized film technology, meaning it has two metals that are evaporated onto a thin film of polypropylene. This construction is designed to provide a low ESR (Equivalent Series Resistance) and a wide temperature range, making it suitable for some temperature-sensitive applications. The construction also provides high stability and low resonance frequency, making it well-suited for use as a coupling capacitor in tuned RC (resistor-capacitor) networks.

In operation, the two metal plates come into contact with one another, allowing the capacitor to store charge. When a voltage is applied to one side of the capacitor, it creates an electric field between the two plates which causes an electric current to flow between them. The current will continue to flow between the two plates until the capacitor has been completely charged. The amount of charge stored on the capacitor is based on the amount of voltage applied to it, and the total charge is referred to as the capacitance.

The MKT1817210404G offers a relatively low ESR (Equivalent Series Resistance) which helps to reduce fluctuations in the current draw from the capacitors. This capacitor is also designed to have a wide temperature range, meaning it can be used in applications that require stability in high and low temperatures. This makes it a good choice for use in applications such as thermal-sensitive circuits, audio and video signal applications, and power supplies.

The MKT1817210404G is a reliable and versatile capacitor, making it suitable for many different applications. Its wide temperature range and low ESR make it an ideal choice for temperature-sensitive applications such as thermal-sensitive circuits, audio and video signal applications, and power supplies. It is also an excellent choice for use in tuned RC (resistor-capacitor) networks and filters, due to its high stability and low resonance frequency.
