Film capacitors are electrical capacitors which feature use of a plastic film as the dielectric. These capacitors are generally divided into two main categories: metallized film capacitors and long metallized film capacitors. The dielectric can be made of PET, polypropylene, polycarbonate, polyethylene terephthalate, polyphenylene sulfide, or a mixture of other materials. It is important to understand the various application fields and working principles of capacitors, especially when making purchasing decisions. This article provides a brief description of what makes the MKT1818322256W capacitor so special and how best to incorporate it into your product.

The MKT1818322256W Film Capacitor is a surface-mount, electrolytic capacitor product which provides a combination of extremely low ESR and long lifetimes. It is engineered to handle high frequency and high temperature application needs. It is constructed using a metalized polypropylene film dielectric with a conformal coating of protective material. This conformal coating is designed to provide long-term reliability and helps protect the capacitors from the effects of temperature and moisture.

When it comes to the working principle of this MKT1818322256W Film Capacitor, it operates using electric displacement in the dielectric material, which is usually polypropylene. The metalized polypropylene capacitors are also known as polypropylene film capacitors and have been gained popularity due to their numerous advantages such as low losses, high-temperature stability and long lifetimes. The electric displacement is created when electrons move through the dielectric and attract the positive ions on the polypropylene film material. The electric field force that is released from the ions and the electrons neutralizes the electric displacement field and results in capacitance.

The main application field for the MKT1818322256W Film Capacitors is for frequency-dependent components and high temperature/high frequency applications. It is mainly suited for use in drives and control systems, power supplies, and power amplifiers. This type of capacitor has high ripple current ratings and can be used in a variety of applications where winding inductance and building capacitance can be minimized. It is especially useful in applications requiring a high level of reliability and high-temperature performance.

The MKT1818322256W Film Capacitor provides reliable performance and durability where other capacitors may not be a viable option. It has a long lifetime, excellent temperature and high frequency performance, and is an ideal addition to a wide range of applications. In conclusion, if you need a capacitor for a wide range of applications, the MKT1818322256W Film Capacitor is the perfect choice for you.
