Film Capacitors

The MKT1818322255W is an industrial-grade film capacitor, consisting of a raw material made of polypropylene film, with a terminal plate that has been built in. This type of capacitor is often used in areas where particularly reliable, stable, and long-term performance is required, such as in motor control, illumination systems, electronic circuits, power supply, electrical locomotives, adjustable speed drive systems, rectification circuits, and inverters. It is also notably used in audio-visual equipment, electrical machines, and temperature and signal control systems.

The raw material of this capacitor is composed of polypropylene film that is uniformly thick and processed with galvanized end plates, as well as isolated air bubbles. The end plates are made of tinned steel. This type of construction is preferred by engineers because of its superior durability, low-loss performance, and high-temperature compatibility.

The working principle of the MKT1818322255W is based on dielectric characteristics. The dielectric is a non-conductive material that, when subjected to an electrical field, causes the material to become electrically non-conductive. This effect is called capacitance, and it is the key factor that governs the maximum operating voltage and current that can be handled by the capacitor. A capacitor with higher capacitance will handle higher voltage and current, while one with lower capacitance is limited to a maximum of 12 volts.

The use of high capacitance also ensures that the capacitor can store more energy for each charge. This makes it an ideal choice for industrial applications where large amounts of energy must be quickly and reliably transferred. Moreover, the higher temperature range makes the capacitor more reliable and versatile in the long term.

The MKT1818322255W also features a superior stability over a wide temperature range and excellent frequency response characteristics. This makes it suitable for precise control applications that require accurate performance over a wide range of temperatures and frequency ranges. Moreover, the use of high temperature plastics ensures a long service life, with a low profile and high efficiency.

The raw material of this capacitor also offers a high creep resistance, meaning that it can withstand the continuous pressure from the device it is installed in. This allows for a steady and continuous performance in a wide range of environmental conditions. Furthermore, the capacitor also features a high self-healing ability, meaning that it will reconnect itself when shorted components are removed.

The MKT1818322255W offers a wide range of applications and can handle up to 12 volts. It is ideal for motor control, power supply, lighting, electrical locomotives, adjustable speed drive systems, rectification circuits, and inverters. It is also widely used in audio-visual equipment, electrical machines, and temperature and signal control systems. Its robust construction, superior dielectric properties, and ability to withstand a wide range of temperatures make the MKT1818322255W an ideal choice for industrial applications.
