Film Capacitors

Film capacitors, also known as plasticfilm capacitors, contain layers of a dielectric film, which are wound together using a conductive foil. This type of capacitor has several advantages over other types of capacitors such as metal and electrolytic capacitors. Film capacitors offer excellent temperature stability, very low ESR (equivalent Series Resistance), and low leakage current. These features make film capacitors ideal for applications where temperature stability and low ESR are critical. Film capacitors are available in both through-hole and surface mount packages.

MKT1817339255G

The MKT1817339255G is a surface mount plastic film capacitor capable of handling high voltage (up to 250V AC) and a wide frequency range (up to 500kHz). This large operating range makes the MKT1817339255G suitable for use in a wide variety of applications, including switching power supplies, DC-DC converters, and power management circuits. In addition, the low ESR and high ripple current rating make the MKT1817339255G suitable for high-frequency and high-efficiency applications.

Application Field and Working Principle

Film capacitors, including the MKT1817339255G, are widely used in power management and control circuits. In these applications, film capacitors provide a stable voltage supply, filtering out high and low frequency signals. Film capacitors are also often used in AC line-filtering circuits, such as those found in household and office electrical appliances, to reduce the amount of noise and other disturbances in the power supply. In high-frequency switching power supplies and DC-DC converters, film capacitors are used as smoothing capacitors to reduce high-frequency noise in the power supply.

The working principle of the MKT1817339255G is simple. The dielectric film, made of plastic or other insulating material, provides the capacitance, while the layers of conductive foil act as the electrodes to provide the electrostatic charge. An electric current is applied to the electrode, resulting in the buildup of an electrostatic charge on the dielectric film. This charge is balanced by a charge of opposite polarity on the other electrode, resulting in a potential difference across the capacitor. This potential difference (or voltage) is held constant, as long as the voltage applied to the electrodes remains constant. When the voltage is removed, the charge is released and the capacitor is returned to its original, blank state.

In addition to providing an electrostatic charge, film capacitors also exhibit low ESR (Equivalent Series Resistance) and low leakage current. The low ESR ensures that the capacitor behaves as an ideal capacitor with minimal losses. The low leakage current ensures that minimal current is lost in the load, resulting in higher efficiency.

The MKT1817339255G is suitable for a wide variety of applications, due to its high voltage rating, low ESR, and wide frequency range. Its low ESR and high ripple current rating make it especially suitable for use in high-frequency and high-efficiency applications. In addition, the MKT1817339255G has a variety of packages and termination options to suit different application requirements.
