Introduction to Film Capacitors

Film capacitors, also known as ‘plastic’ or ‘polyester’ capacitors, are electrical components used to store and release electrical energy. They are widely used across a variety of applications, including power supplies, signal processing and control circuits, and an increasing number of consumer applications. This article will cover the MKP1845422104 and its application field and working principle.

Types of Film Capacitors

Generally speaking, there are four main types of film capacitors. These include metalized polypropylene (PP), polycarbonate (PC), and polyester (PE) capacitors. There are also more specialized capacitors, such as those with ceramic dielectrics, foil-back polypropylene and metalized polyester.

MKP1845422104 Application Field and Working Principle

The Model MKP1845422104 is a radial lead type Film Capacitor from Kemet. It is a polypropylene-film capacitors (MKP), rated at 0.047uF. It is designed for a variety of applications, including AC ripple current suppression, snubber circuits, RF blocking, active filter, audio, and switching power supplies.

The MKP1845422104 is a non-polarized, radial-leaded capacitor with a voltage rating of 330V AC, capacitance of 0.047uf, and a dielectric of polypropylene film. Its capacitance tolerance is ±10%, its temperature coefficient is ±3,000ppm/°C, and its self-healing characteristics are 98%, with a leakage current of no more than 0.1mA at 20°C and rated voltage. The MKP1845422104 polypropylene film capacitor also features low dissipation factor, low ESR, and high ripple current ratings.

The MKP1845422104 capacitor works by utilizing a dielectric material like polypropylene film. The film is made up of two electrodes that are separated by a dielectric material. When a charge is applied to one end of the capacitors, an electric field is created by the charge and is held in the dielectric material. This electric field stores energy in the form of a charge. When the charge is released, the electric field collapses, releasing the stored energy.

Uses of the MKP1845422104 Capacitor

The MKP1845422104 capacitor can be used in a variety of applications, including AC ripple current suppression, snubber circuits, RF blocking, active filter, audio, and switching power supplies. In power supplies, the film capacitors help to reduce the amount of voltage drop across it, providing a smoother power supply. In RF blocking applications, the film capacitors can block RF signals from entering the circuit by absorbing the energy and dissipating it as heat. In active filter applications, the capacitors are used to filter out unwanted high-frequency signals.

The MKP1845422104 is also widely used in audio applications. Its high-current and low-inductance capability makes it perfect for applications like audio crossover networks, guitar effects, and speaker crossover systems. At higher frequencies, such as in reverberation circuits, the capacitors can be used to smooth out any potential glitches.

Conclusion

The MKP1845422104 capacitor is a polypropylene-film capacitor that is designed to be used in a variety of applications. Its low dissipation factor, low ESR, and high ripple current ratings make it a reliable and efficient component for a variety of applications, such as AC ripple current suppression, snubber circuits, RF blocking, active filter, audio, and switching power supplies.
