Film Capacitors – MKT1820618015 Application Field and Working Principle

Film capacitors (also known as MKT1820618015) are widely used in a variety of applications due to their inherent various advantages such as high frequency, low dielectric absorption, high voltage breakdown voltage, and so on. They are available in a variety of configurations, such as Surface Mount, Through-Hole “T” type, Cylindrical, etc. by using different types of materials and packaging methods.

Introduction to MKT1820618015

MKT1820618015 is the part number of a Film Capacitor, specifically made from Polyester film with metallized electrodes. It’s an SMD type Film Capacitor having the rating of 10µF, voltage rating of 50 Volts and capable of operating between -40℃ to 85℃.

Application Fields of MKT1820618015

The MKT1820618015 could be used in a variety of applications like Motor Drive, Power Supply, Automotive, and Lighting systems. The small size, high voltage, and low loss allow its deployment in a variety of applications where space is limited. It’s suitable even for portable and handheld electronic products. The high insulation and low dielectric absorption properties make it suitable for high frequency applications including filters, RF decoupling and cable shielding. In motor drive applications, they are used for transient protection, power factor correction, and inverter circuit protection.

Working Principle of MKT1820618015

MKT1820618015 capacitors are formed by winding two pieces of Polyester film and two pieces of aluminum film. They are then enclosed by a cylinder shape paper cover known as Paper sleeve perforated paper. These capacitors mainly work on the theory of electrostatic induction. The electrical field is created between the two electrodes, and the field induces the electric current that can be stored in MKT1820618015. Such electric currents, when they traverse the dielectric material, will get stored in the capacitor and it will start showing capacitance.

The benefit of a Film capacitor is that they have high insulation resistance, low losses, and high-power capability. The low losses because the dielectric material does not absorb a lot of energy, while the high insulation resistance ensures that they are not affected by moisture and other environmental factors.

Since the MKT1820618015 is a non-polarized capacitor, meaning its terminals do not have a positive or negative side, it can be used for a wide range of AC signal applications. But as their capacitance value is relatively low compared to other capacitor types, they should be avoided when high voltage/current and large capacitance are needed.

Conclusion

In short, Film Capacitors, like the MKT1820618015, represent a great solution for portable, high frequency, and medium voltage applications. They can be used in amplifier circuits, power factor correction, and transient suppression, with a wide range of sizes and capacitances. The low losses, small size, and non-polarity make them a unique and versatile solution for a variety of applications.
