Film Capacitors

Film capacitors are widely used in today’s electronics industry due to their superior characteristics and reliable performance. The MKT1817247015D, a film capacitor, is no exception.

MKT1817247015D Application Field

The MKT1817247015D is ideally suited for use in diverse applications, including general purpose filtering, timing control, waveform shaping, and data transmission in power electronic devices, computers, and digital electronic equipment. This capacitor is designed for use in devices working on AC and DC voltages below the rating voltage.

For DC applications, it offers low leakage current and low equivalent series resistance (ESR), which ensure low power consumption and long operating life. For AC applications, it features low capacitance variation with voltage, which ensures high-precision performance. It offers superior frequency characteristics, with a high level of accuracy. This means that the capacitance remains accurate even when the voltage fluctuates or the frequency changes.

MKT1817247015D Working Principle

The MKT1817247015D is based on a dielectric polymer film and a metal capacitance structure. Its structure consists of a top plate, a bottom plate, and an embedded metal center plate. In this configuration, both the top and bottom plates are covered with additional metal electrodes, and the whole assembly is sealed inside a metal case. When a voltage is applied to the two electrical contacts, the electric field penetrates through the metal electrodes and spreads between the top and bottom plates. This creates an electric field that polarizes the dielectric polymer film and produces capacitance.

As voltage increases, the electric field that permeates between the metal plates increases as well. This field adds to the effective capacitance of the device and allows it to maintain its performance with increasing voltage levels. In addition to increasing capacitance, the MKT1817247015D also has the benefit of contributing to higher insulation impedance and better circuit stability when used in AC applications.

The capacitance value of the MKT1817247015D remains stable even when the temperature changes. This is due to its low temperature coefficient of capacitance. The polymer film is also designed to be self-healing, which allows it to recover from any microscopic damage that can occur over time or during usage.

Conclusion

The MKT1817247015D is an ideal choice for applications that require reliable performance, high accuracy and stability, and a long operation life. Its combination of low ESR, high stability, and low temperature coefficient of capacitance make it well suited for general-purpose filtering, timing control, waveform shaping, and data transmission in power electronic devices, computers, and digital electronic equipment.
