Film capacitors, also known as plastic capacitors or polyethylene naphthalate (PEN) capacitors, are a type of capacitor characterized by a dielectric material composed of a film, typically a thin plastic film. They are commonly used in many areas of electronics, such as microwave ovens, television sets, and audio equipment. The MKP1839427124HQG is a film capacitor that is designed for high frequency applications.

The MKP1839427124HQG is a radial 4- and 5-pin leaded capacitor, and it features a ceramic, metallized polypropylene dielectric material. The operating temperature range of the capacitor is -55 to 105°C, and the capacitance tolerance is 0.5%. It has a particularly high self-healing capability due to the use of ceramic and metallized dielectrics, which allows it to handle transient overvoltages without damage.

The main application fields of the MKP1839427124HQG include power tools, automotive, work lights, measurement equipment, and industrial installation. The high temperature range and self-healing property of the capacitor make it highly suitable for power applications as it can withstand temperatures of up to 105°C. The metallized polypropylene dielectric also prevents damage from transient overvoltages, making it suitable for automotive and measurement equipment applications.

The working principle of the MKP1839427124HQG is based on the dielectric properties of the ceramic and metallized polypropylene material used as the dielectric material. When a voltage is applied across the capacitor, it creates a voltage gradient across the dielectric material, which creates an electrical field that forces the electric charges to move to the surface of the conductor and form an electric dipole. The electrical dipole then creates a current through the material. This current will flow from one end of the capacitor to the other and can be measured with an appropriate instrument.

The operating frequency of the MKP1839427124HQG is from 10kHz to 1MHz, with a rated voltage of 250V or 200V. The rated current is 25A at 25°C, and the insulation resistance is greater than 1000MΩ. The capacitance range is 0.0047 to 0.68μF, and the temperature coefficient is +/-15%.

The MKP1839427124HQG is a highly versatile film capacitor that is suitable for many applications in automotive, power tools, industrial installations, and measurement equipment. Its high temperature range, low temperature coefficient, and self-healing capability make it an ideal choice for many electronics applications, and its working principle is based on the dielectric properties of the ceramic and metallized polypropylene dielectric.
