Introduction

Film capacitors, also known as polyester, polypropylene, and polycarbonate film capacitors, are widely used in various electronics applications, such as filtering and decoupling. Film capacitors are non-polar, which provides them advantages over electrolytic capacitors in audio and RF applications due to the lack of inductance, superior linearity and frequency responses, and low distortion. MKT1813468256 is a type of film capacitor developed by a leading manufacturer and is designed for general circuit and power applications. In this article, we will discuss the application fields and working principles of MKT1813468256.

Application Field

MKT1813468256 is a general-purpose film capacitor that can be used in various applications. Its features make it suitable for power and other DC/AC circuit applications, such as electric motors, automotive electronic equipment, air conditioners, home appliances, and electronic machines. It is also suitable for inrush current suppression, pre-stabilization of load discharge, and filter electrification of noise from power-supply equipment or power-supply lines.

Features

MKT1813468256 has the following features:

• High insulation resistance: The insulation resistance of MKT1813468256 is up to 10¹²Ω. The high insulation strength exhibits excellent noise reduction and stability, providing an ideal solution for power source applications.
• High reliability: This product is produced with modern technologies to ensure its reliable performance. The proprietary proprietary coating process with advanced winding technology and rigorous sintering resonance ensure its stability and longevitiy.
• High impedance: The high impedance capability of MKT1813468256 helps reduce current through the capacitor. This reduces the generation of heat, which is especially useful in high-power applications.
• Low leakage current: The leakage current is low, with no notable resistive characteristics, so the capacitor is suitable for applications where low noise is desired.
• Low loss: The loss of MKT1813468256 is low; it has excellent high-frequency characteristics that make it suitable for audio and RF applications.
• Low ESR: MKT1813468256 features a relatively low ESR of 8.5mΩ, which means that it can provide relatively high current with minimal losses.

Operating Principle

MKT1813468256 works by utilizing the dielectric properties of an isolated dielectric film. This film is usually 0.01‒0.02mm thick and consists of a polyester, polyproylene, or polycarbonate film. The dielectric film is then rolled into a cylinder and the metal end plates, usually made of aluminum or zinc, are attached to each side. The capacitor is then wound with two sets of insulated conductors which are connected internally.In operation, an electric current is passed through the isolated dielectric film, causing the electric field to accumulate energy within the dielectric film. This energy stored in the dielectric film forms an electric field, which opposes the electric current and causes a voltage difference across the two plates. This voltage difference is the voltage the capacitor can provide. The capacitance of the capacitor is proportional to the area of the plates and inversely proportional to the distance between them.

Conclusion

In conclusion, MKT1813468256 is a film capacitor designed for general circuit and power applications. It features high insulation resistance, high reliability, high impedance, low leakage current, low loss, and low ESR. Its working principle involves generating an electric field using an isolated dielectric film, and its capacitance is proportional to the area of the plates and inversely proportional to the distance between them.
