Introduction

The MKP1848612094P4 is a type of film capacitors designed specifically for stabilizing current and voltage with extremely low distortion. Its application fields are mainly audio equipment, power supplies, PFC, industrial automation, and telecom. A few of its features include wide voltage range, low ESR, high insulation resistance, and high-temperature operation capability. It is usually used in circuits requiring power filtering or transient pulse protection for high-precision and low-distortion operation.

Types of Film Capacitors

Film capacitors are grouped into four families. The MKP1848612094P4 film capacitor is classified as a Metallized Polypropylene Film (PP) capacitor.

Polyester Film Type (RFB)

The polyester film type capacitors are designed for general purpose applications and are particularly useful in high frequency and pulse ranging uses. The capacitor is made of a dielectric polyester film and coated with metal on both sides. It is characterized by a wide variety of standard capacitances, high insulation resistance, and a broad temperature range.

Polypropylene Film Type (PP)

The polypropylene film type capacitors, such as the MKP1848612094P4, feature higher insulation resistance and broader temperature range than the RFB type, making it suited for high-precision and low-distortion circuits. As opposed to the PP type, it is constructed with a layer of polypropylene film, one metal coating, and a dust back layer of polyester film.

Polycarbonate Film Type (PC)

The polycarbonate film type capacitors are designed for high-frequency and high-voltage applications, featuring good dielectric properties, small size, and high capacitance. Its dielectric is made of a polycarbonate film, and is made of one metal coating and a dust-back layer of polycarbonate film.

Fluoropolymer Film Type (PVDF)

The fluoropolymer film type capacitors are made of a fluoro-resin dielectric, one metal coating, and a dust-back layer of polyester film. It is characterized by its good high-frequency characteristics, outstanding insulation resistance, and superior dielectric strength. It is typically used in specialist applications, such as X-ray protection circuits.

Working Principle

Film capacitors, such as the MKP1848612094P4, are electrical components that store and transfer electrical energy. They consist of a dielectric material and a pair of conductive plates that store electric charge when a voltage is applied to them. When two conductive plates are brought close together, the amount of charge stored will increase.The moment a voltage is applied to a film capacitor, the positively charged plate of the capacitor is connected to the positive terminal of the power source, while the negatively charged plate of the capacitor is connected to the negative terminal. This arrangement will cause the positive charge to be attracted to the negative terminal and the negative charge to be attracted to the positive terminal.Once the capacitor reaches its maximum static charge, the electrons cannot flow any further, and the circulation stops. This arrangement will allow the capacitor to store the charge, and this will remain until the voltage is removed from the capacitor.The tiny amount of voltage that can be stored in a film capacitor is known as its capacitance. The value of the capacitance is determined by the material of the dielectric, the spacing between the two plates, the surface area of each plate, and the arrangement of the dielectric along the plates.

Conclusion

The MKP1848612094P4 is a type of film capacitor designed for low-distortion circuit applications specifically. It is classified as a Metallized Polypropylene Film capacitor and is characterized by its wide voltage range, low ESR, high insulation resistance, and high-temperature operating capability. The working principle of the film capacitor is explained above, and it stores electric charge when a voltage is applied to it, and the value of its capacitance is determined by the material of its dielectric, spacing between the two plates, surface area of each plate, and the arrangement of the dielectric along the plates.
