Film Capacitors

Film capacitors, also known as plastic film capacitors, are a type of capacitor with the dielectric material between the plates in the form of a plastic film. Film capacitors are used for a variety of applications, from high frequency systems to general-purpose low voltage circuits.The 305PHB400K2H is a film capacitor of the 305PHB series, These capacitors are designed for use in high-voltage, high-frequency and general-purpose applications where a wide operating temperature range is desired. The design of this type of capacitor is such that the capacitor can withstand high voltage surges without operational degradation and leakage problems at higher temperatures.The 305PHB400K2H features two aluminum foil electrodes which are separated and insulated by a dielectric material. The dielectric material is usually a polyethylene or polypropylene plastic film which is then coated with a layer of metal oxide, metallized, or conformally coated for additional protection. This combination ensures that the effective capacitance and dissipation factor are maintained even after long operating hours and at high temperatures.The 305PHB400K2H offers a wide array of advantages including high-temperature stability, high-voltage tolerance, and low losses. The operating temperature range is from -25 to +125°C. It also exhibits low leakage current and excellent self-healing when exposed to electrical stress. With a frequency range between 0 to 100kHz, the 305PHB400K2H can be used in high frequency applications such as for audio amplification.The working principle of the 305PHB400K2H is based on the concept of capacitance. Capacitance is the capacity of an electrical circuit to store energy between two conductors separated by a dielectric material. When a voltage is applied on either side of the capacitor, electric charges are stored in the form of electrostatic fields in the dielectric. This allows current to be transferred between the two conductors, thus forming an RC circuit.The 305PHB400K2H is ideal for applications requiring high voltage, high frequency, and low voltage circuits. Its design manufactures superior performance even over a wide temperature range, with excellent electrical specs, high reliability, and a long life expectancy. The applications of this film capacitor include power transmission and distribution, DC to DC converters, automotive ignition systems, electric fans, motors, and more. Additionally, the 305PHB400K2H can even be used for temperature control systems, signal processing, switching power supplies, and high frequency communication systems.Overall, the 305PHB400K2H film capacitor is a reliable, high-performance device that is perfectly suited for a range of electrical systems. Its excellent construction and dielectric material ensures that it can withstand a range of extreme conditions without any operational degradation or leakage problems. Furthermore, its superior capacitance and low dissipation factor offers superior performance in terms of voltage, current, power loss, and noise suppression. As such, it is a great choice for any of high voltage, high-frequency, or general-purpose applications.
