Film capacitors, also known as plastic film capacitors, are capacitors that use a plastic film as the dielectric material. The KP1830210015W is a film capacitor from KEMET, described as a “General Purpose Class X2 Capacitor.” It comes in a leaded package and its capacitance rating ranges from 0.47 to 10.0 μF. The Joule rating for this capacitor varies by voltage; at 275VAC it is 3.2J, at 275VDC it is 1.8J, and at 275VDV it is 7.8J. The expected life of this capacitor is 2000 hours at an ambient temperature of 85°C.The KP1830210015W is designed for use in a variety of applications, including motor run/start operations, general-purpose filtering, power electronics, power supplies, and HVAC. Its aluminum case ensures superior heat dissipation, allowing it to be used in high temperature applications, and its metallized silver-zinc film provides good self-healing characteristics. It is also exceptionally resistant to humidity, so it can be used in wet environments.The capacitance of this capacitor is managed by separating the dielectric material into two leaves, and forming finger contacts between them. As an electrical charge is applied, the dielectric material is temporarily polarized, increasing the capacitance value. This increase in capacitance value results in higher capacitance performance and improved efficiency.The working principle of a film capacitor is based on the concept of capacitive reactance. When an alternating current is passed through the capacitor, its terminals are alternately charged and discharged. This process results in an electromagnetic field that stores energy, and this stored energy is what gives the capacitor its ability to act as an insulator and store electrical charge.In addition to the regular function of storing energy, film capacitors are also used for energy smoothing purposes. Due to the fact that they are able to hold a more constant capacitance across different frequency ranges, they are often used in power supplies, voltage regulation, and resonance applications.The KP1830210015W offers suitability for many general-purpose and HVAC applications. Its high dielectric strength, stability, and high capacitance make it an ideal choice for a wide range of uses. Whether used for synchronous motors, inductive loads, or power supplies, the KP1830210015W is a reliable and durable solution that is sure to exceed expectations.
