Film Capacitors

Film capacitors are gaining in popularity due to their low equivalent series resistance (ESR), self-healing mechanisms, low temperature coefficient, and other characteristics that make them well-suited for use in various types of electronic circuits. One particular model, the MKT1817322014W, has been especially popular in recent years. This article will explain its application field and working principle.

Application field: The MKT1817322014W is a film capacitor that is most suitable for use in high-frequency, high-voltage, high-pulse power, and more. It is capable of withstanding voltage up to 2.25kV, and its stable capacitance makes it well-suited for high-frequency applications. This makes the MKT1817322014W an ideal capacitor for applications such as snubber, power factor correction, lighting, motor drives, and other types of high-power systems.

Working principle: The MKT1817322014W is constructed from two thin films of polypropylene and metalized electrodes. These films are tightly wound together to form a cylindrical core, which is then inserted into a round paper-wound case. This structure also helps to provide superior self-healing capabilities. When the voltage is increased, the MKT1817322014W will start to store energy, allowing it to self-heal any small faults that may develop. The breakdown voltage of the MKT1817322014W is around 50% higher than that of a standard film capacitor, making it highly reliable in applications where high voltage is required.

The MKT1817322014W also has a relatively high equivalent series resistance (ESR). This helps to ensure that the capacitor does not overheat in higher frequency circuits, and also helps to reduce any excessive capacitance variations that may occur in some applications. This makes it ideal for those circuits which require high pulse regulation.

Finally, the MKT1817322014W is also highly resistant to temperature. This makes it ideal for military applications and any other applications which are exposed to extreme temperatures. In addition, its high surge capability and dissipation also make it well-suited for heavy-duty applications.

In summary, the MKT1817322014W is a highly reliable film capacitor which is ideal for various types of applications. Its low ESR, self-healing properties, high pulse regulation capabilities, and temperature stability all make it an ideal choice for many types of applications, from motor drives to snubber capacitors.
