Film capacitors or film dielectric capacitors are electronic components that are highly reliable for use in many applications. It is typically used for high-voltage, microwave transmission line applications, telecommunications, motor control, and in-circuit protection for AC motors. MKT1817318016 is a film capacitor which is manufactured by Murata. It is a high-voltage film capacitor with a radial lead design, making it suitable for use in many of the applications mentioned above. This article will explain the application field and working principle of the MKT1817318016.

Application Field of MKT1817318016

The MKT1817318016 film capacitor is primarily used in applications such as data and signal transmission, electromagnetic interference suppression, and AC motor protection. It is ideal for use in high-voltage applications such as high-voltage power supplies, high frequency circuits and impedance matching in RF circuits.

Data and signal transmission applications can benefit from the MKT1817318016’s capacitance range of 0.047 - 0.47 µF and its maximum working voltage of 5,000 V AC. Its low equivalent series resistance (ESR) and high temperature coefficient of capacitance (TCC) make it ideal for mitigating the effects of electromagnetic interference and suppressing noise from power supplies. Its wide operating temperature range (-55 to +125℃) also make it suitable for use in a wide variety of electrical and electronic systems.

Working Principle of MKT1817318016

The MKT1817318016 is a film capacitor in a radial lead design. It is composed of a metallized polypropylene film dielectric layer which is encased in an epoxy coating. The film dielectric layer is sandwiched between two electrodes; one of which is an electrically conducting, self-healing metallic layer that ensures good electrical contact with the electrodes and a good electric insulation. In addition, the capacitor is also equipped with an internal terminal which helps to prevent accidental short circuits.

The basic operating principle behind film capacitors is the same for all film capacitors. As with any capacitor, when a voltage is applied to the electrodes, a capacitance value is established in the dielectric material between the electrodes. The capacitance value is determined by the area of the electrodes and the dielectric constant of the dielectric material. The MKT1817318016 is able to achieve high dielectric constant values due to its metallized polypropylene film dielectric layer.

The MKT1817318016 is a reliable, high-voltage film capacitor that is available in a variety of configurations and can be used in a wide range of applications. Its metallized polypropylene film dielectric layer makes it particularly suitable for high-voltage applications where high dielectric constants are required. As well, its radial lead design allows for easy installation and facilitates proper heat dissipation. All of these features make the MKT1817318016 a great choice for high-voltage applications where reliability is a necessity.
