Film Capacitors

Film capacitors, also known as plastic film capacitors, are passive electronic components made entirely of dielectric material and are most commonly made of polymer films.

Because of their unique structural characteristics, film capacitors are a versatile and highly reliable electrical component used in a wide range of electrical and electronic systems.

The MKP383247200JFM2B0 capacitor is a polyester film capacitor and is designed for power electronics applications. This type of capacitor is constructed using polyester (PET) film, which is highly durable, stable, and highly resistant to breakdown. This capacitor has a high insulation resistance, high dielectric cycling capability, low losses and minimal inductance.

Film capacitors, including the MKP383247200JFM2B0, are well suited for many different applications, ranging from power supplies, inverters, and motor controllers to car audio systems, computing, and avionics. They are often used in power electronic circuits, where high ripple current ratings and low ESR characteristics are required. They are also used for smoothing, timing, bypassing and other optimal electrical operations.

The working principle of a film capacitor is based on the basic principle of electric capacitance. Electric capacitance is the ability of two electric conductors to hold charge when a potential difference exists between them. As electric charge builds up on the capacitor terminals, it causes a displacement of electrons within the dielectric material, creating an electric field. This electric field stores energy and can be released when the voltage across the capacitor is reduced, providing power to connected loads.

When voltage is applied to the capacitor, electrons move onto the negative terminal and an equal amount of charge moves onto the positive terminal. This is known as charging the capacitor. During this process, excess energy is stored in the electric field and can be released as needed. However, when the voltage is removed, the electric field rapidly collapses, allowing the stored energy to be released back into the system.

The MKP383247200JFM2B0 is a high performance film capacitor that can be used in a variety of power supply, motor control, and car audio applications. It has a capacitance value of 470pF, a voltage rating of 200V, a ripple current rating of 2A, and a temperature range of -40°C to +85°C. This capacitor has an insulation resistant of 20,000 MΩ/100 volts, and a leakage current of 0.3 μA. It is also UL approved, RoHS compliant, and has a rated lifetime of 1000 hours.

In summary, film capacitors like the MKP383247200JFM2B0 are a versatile and reliable capacitor that can be used in a variety of power electronics applications. They are used to store and release energy, and can help maintains regulation of voltage spikes or drops. With a high insulation resistance, high dielectric cycling capability, and low losses, film capacitors are invaluable components for many electrical and electronic systems.
