Film Capacitors

Film capacitors are a type of capacitor that uses thin plastic films as its dielectric and electrodes. They are employed in a wide variety of electrical and electronic circuits for functions such as timing, signal coupling, power supply filtering, and voltage regulation. Film capacitors are classified by the type of dielectric film used—usually Mylar, polyethylene terephthalate (PET), polypropylene, polystyrene, or any other polymer. The components in the 160473J630G series of film capacitors employ a Mylar dielectric. In this article, we will explore the working principle and applications of 160473J630G film capacitors.

160473J630G film capacitor working principle

Film capacitors use a thin dielectric film for insulation between two metal electrodes. The dielectric is most commonly made from Mylar; however, other types of dielectrics can be used for specific applications. The two metal electrodes are then encapsulated, typically with epoxy or polyurethane resin, to form the complete device. When a voltage is applied across the two electrodes, a dielectric polarization occurs. This induces an electric field that stores electrical energy, resulting in the characteristic capacitive behavior.

The energy-storing capacity of a film capacitor is determined by the thickness, width, and permittivity of the dielectric. The width and thickness of the dielectric can be adjusted to achieve a specific capacitance value, as well as a desired operating voltage. The permittivity of the dielectric film will determine how much charge the capacitor can store per unit voltage. A higher permittivity value will result in a higher capacitance.

Film capacitors from the 160473J630G series are commonly used in audio equipment, such as speakers, amplifiers, and equalizers. They are also employed in motor speed and torque control circuits, where their high dielectric permittivity provides stability and precision. Additionally, they are employed for voltage-regulating purposes, as they can accurately store and release electrical energy.

Film capacitors from the 160473J630G series are also ideal for power supply filtering applications. Their high dielectric permittivity allows them to filter out unwanted high frequency signals from the power supply, thus providing a clean voltage source to the circuit. Film capacitors can also be used in circuit timing applications, as their capacitance value can be accurately adjusted to achieve desired timing parameters.
