Film Capacitors

B25835B1225K17 application field and working principle

Film capacitors are a type of capacitor often used in electronic applications due to their relatively small size, high stability, and low cost. They typically feature insulation layers between conductors which are made up of a wide variety of plastic films. This range of materials provides a wide range of options, allowing for multiple customized designs to meet specific application requirements.The B25835B1225K17 is a film capacitor designed to operate in a wide range of temperatures. It is a cylindrical device with a metal can body enclosing a set of film layers. The capacitor contains two thin aluminum foil electrodes, on which the plastic films are wound. Between the two aluminum foil electrodes, an insulating dielectric is added to separate the two electrodes, which will also determine the capacitance value of the capacitor.The B25835B1225K17 is ideally suited for automotive, industrial, and commercial applications requiring high capacitance in tight spaces. This film capacitor offers a wide temperature range (-40°C to +105°C), high stability, and long life. It is a reliable, low-cost, high-performance capacitor that is used for a variety of applications, such as motor drives, HVAC, lighting, oil and gas, electronic circuits, and more.The B25835B1225K17 works by allowing current to flow through it, but only allowing a certain amount of voltage to pass through. This is done by creating a non-conductive space between two conductive pieces of metal, called the dielectric. The dielectric material used in this capacitor is polypropylene, which provides excellent insulation capacity and stability.When a voltage is applied, the electric field generated separates the molecules of the dielectric, creating an electric dipole moment. This electric dipole forms two small capacitors between two of the metal electrodes, which is known as the capacitance of the capacitor. The capacitance of the capacitor is directly related to the amount of electric charge stored when voltage is applied.The B25835B1225K17’s high heat dissipation capabilities make it ideal for applications which require a large amount of power. Its low impedance capability ensures a reliable current collection when current is drawn from the capacitor. In addition, its high surge capacitance allows for high switching speeds and improved power-line noise immunity.Overall, the B25835B1225K17 is an ideal choice for a wide variety of applications due to its relatively small size, high capacitance, and low-cost. Due to its ability to operate at high temperatures and across a wide voltage range, it is well suited for industrial and automotive applications. Furthermore, its long life expectancy and high stability make it a great choice for any application requiring a reliable, high-performance film capacitor.
