Film Capacitors

Film capacitors, also known as plastic film capacitors, plastic film dielectric capacitors, or polymer film capacitors, are a type of capacitor commonly used in electronic circuits. They are made up of plastic film as the dielectric material and metal electrodes deposited on the film for the two plates of the capacitor. These capacitors possess excellent insulation resistance, low loss, high insulation to strength ratio, low dielectric absorption, low inductance, and other advantages.

715P47396LD3 Application Field

The 715P47396LD3 film capacitor is a high-performance capacitor ideal for a range of applications, namely audio, AC electric motors, DC electric motors, motor drives, photovoltaic (PV) inverters, and alternative energy applications. It has a wide temperature range (-55°C to 105°C), a high relative dielectric constant (K value), and low dielectric losses (30ppm/℃). Its capacitance range is 0.1uF to 10uF.

Working Principle

The 715P47396LD3 capacitor works on the principle of electrical current and voltage. Electrons are attracted to and form a metallic layer on one side of the capacitor, forming the positive electrode. When an electrical charge is applied to the capacitor, the positive electrode attracts electrons, creating a positive electrical charge on the other side of the capacitor. As the voltage increases, the negative electrode, which has fewer electrons, stores more energy.

This stored energy creates a dielectric field across the two metal electrodes, and the negative charge of the electrons pushes against the positive charge of the opposite electrode. As the voltage increases, the energy stored between the two electrodes also increases. When the voltage is released, the stored energy is discharged, producing a uniform electrical current.

Conclusion

The 715P47396LD3 film capacitor is an ideal choice for a wide range of electrical and alternative energy applications. It features a wide temperature range, high relative dielectric constant, and low dielectric losses. It works on the principle of electrical current and voltage, storing energy between two electrodes and producing a uniform electrical current when the voltage is released. This makes it highly efficient and reliable.
