Film capacitors, also known as plastic film capacitors, plastic audio capacitors, paper-plastic capacitors, film dielectric capacitors, and metallized film capacitors, are passive electronic components that store and discharge electrical energy. They are made using thin film dielectrics including Mylar, polystyrene, PEN, polycarbonate, polypropylene, polyester, Kynar, and sometimes lithium tantalate, and are formed into cylindrical-shaped capacitors. These components are used for electrical power management in an array of electrical and electronic products, including consumer electronics, home appliances, and automotive equipment.

The MKT1818382016 is one of the most widely used film capacitors available today. It is composed of a polypropylene thin film dielectric, with polyester reinforced film and a metallized aluminium electrode. It offers a wide capacitance range of 1nF to 2.2µF at a rated voltage of 250V AC and is available in five different dimensions, allowing for easy integration into PCBs. This capacitor offers great stability, low losses, high energy density, and excellent surge voltage capability. It is equally suited for use in energy storage, smoothing, decoupling, and blocking applications.

The working principle of the MKT1818382016 works by creating an electric field between two charged electrodes. This electric field is then responsible for collecting and storing energy from the AC power source. The capacitor blocks the current from rising more than a certain level and helps maintain the steady voltage of any circuit.

On the application side, this capacitor is widely used for load power applications. It helps reduce the current and voltage stresses experienced by the power line and reduces the transients caused when switching power connectors on and off. This component is also ideal when used as a power resistor for current limitation or voltage smoothing, as it keeps the voltage within acceptable limits. Its use in pulse-width-modulation systems also helps to ensure accurate pulse waveform and is effective in producing high resolution waves without any form of distortion.

Additionally, the MKT1818382016 is also frequently used in audio applications. Its low-loss characteristics are useful for increasing the power of the signal and improving the sound quality within audio systems. It is also ideal for use in filtering applications, especially in automotive equipment, as it allows for fine-tuning of the sound. It also finds use in harmonic distortion compensators, where it increases the failure rate of semiconductors when driving AC loads.

Overall, the MKT1818382016 provides an excellent combination of high stability, low losses, high energy density, and excellent surge voltage capabilities, making it the film capacitor of choice for a variety of applications. It is an invaluable component for any engineer designing for energy storage, smoothing, decoupling, and blocking applications, as well as in audio applications such as the filtering and harmonic distortion-compensating.
