Film capacitors are electrolytic-type capacitors that use a thin plastic film as the dielectric medium rather than the paper-foil-foil dielectric used in standard aluminum electrolytic capacitors. This type of capacitor offers several advantages over its aluminum counterpart, particularly in terms of high-frequency performance, efficiency, and reliability.

The MKT1813347404G is a film capacitor available from TDK. This capacitor is a radial leaded type, housed in a 4-pin package with dimensions of 18mm × 13mm × 4.0mm. It is rated for a capacitance of 1µF, with a maximum working voltage of 25VDC. The capacitor has excellent high frequency characteristics, with a working frequency range from -55 to 125°C with a rated ripple current of 200mA, making it ideal for use in various audio electronics and noise filters, as well as high-end power supplies.

The MKT1813347404G film capacitor consists of a thin plastic film, usually plasticized Polyester, as the dielectric medium and electrodes. The plastic film is coated with metal electrodes, usually aluminum or silver, forming the positive and negative terminals. The electrodes are separated by an insulating layer to prevent short circuiting.

The working principle of the capacitor is straightforward. During AC operation, the current alternates and passes through both the positive and negative terminals of the capacitor. As the current alternates, the capacitor charges and discharges in a cyclical fashion, and the process results in a steady energy flow. This results in the capacitor acting as a storage device for electrical energy, allowing it to be used for any number of applications.

The MKT1813347404G film capacitor is an effective and reliable choice for power supplies, energy storage, noise filtering, and various audio and telecommunications applications. Its high frequency performance makes it perfect for applications in these fields, as well as for use in any situation where higher levels of reliability and efficiency are needed over traditional electrolytic capacitors. As such, it provides an excellent solution for designers seeking a more cost-effective and reliable capacitor.
