474MSR100K Datasheet/PDFFilm Capacitors
Film capacitors are well known for their dielectric strength and high real capacitance values. In the context of power management and measurement, a film capacitor is defined as a capacitor with an insulation film as a dielectric between its two electrodes. Film capacitors can be of different types, depending on the material used as insulation film such as polycarbonate, polyester, polypropylene, and polystyrene. The most used material is polypropylene, and it is also the most expensive material used for making film capacitors.
The 474MSR100K is a type of film capacitor from the 474MSR series manufactured by General Electric. The 474MSR100K is a miniature axial lead film capacitor and is ideal for applications such as buffering, decoupling, and filtering. It has a capacitance value of 100kF, a working voltage of 630V, and a rated ripple current of 600mA.
Application Field
The 474MSR100K film capacitor provides excellent performance across multiple industries. It is commonly used in medical equipment, automotive and power electronics, including power converters, motor drives, and switch-mode power supplies. Due to its high dielectric strength, low cost, and ability to easily handle high ripple currents, the 474MSR100K is a popular choice for these industries. Furthermore, it is also used in radio frequency, audio, and lighting applications.
Working Principle
A film capacitor works on the principle of dielectric polarization. A dielectric is an insulating material with a relative permittivity higher than that of air and lower than that of a conductor. In a film capacitor, two electrodes are separated by a thin dielectric sheet. The dielectric sheet helps in storing electrical charge, which is the basis of working of the capacitor. When a voltage is applied to the capacitor, the electric field builds up between the electrodes resulting in a piling up of charges. This accumulation of charges causes a change in the dielectric material, causing the electric field to die and the capacitor to charge.
Generally, film capacitors are used as alternating current (AC) capacitors due to their high frequency characteristics and low losses. Furthermore, they have several advantages over other types of capacitors such as ceramic capacitors, electrolytic capacitors, or mica capacitors, which makes them very suitable for various applications. Film capacitors have wide working temperature range and high current handling capability. Furthermore, they have high dielectric strength, low parasitic inductance and low microphonic levels.
