Film Capacitors

Film capacitors, or film dielectric capacitors, are a type of capacitor that uses a thin plastic film as its dielectric. The type of film used in film capacitors is typically polyester, polypropylene, polystyrene, or a polyvinylidene fluoride (PVDF). These film capacitors offer a wide range of capabilities and can be used in a variety of applications, depending on the type of dielectric material used. The BN074K0103K model of film capacitor is designed to meet a wide range of applications and has some of the highest capacitance values available in a small size.

The BN074K0103K is a low voltage aluminum electrolytic capacitor that features a -20% to +80% deviation tolerance. It offers a wide range of capacitances, with values ranging from 1 μF to 220 μF. The voltage rating range on this model is 6.3 V to 50 V and the reference temperature range is -40°C to +105°C. It also comes in an axial package design, allowing for easy mounting and installation.

Application Field and Working Principle

The BN074K0103K model of film capacitor can be used in a variety of applications, including power supplies, LED lighting, home appliances, and electronic equipment. In particular, this type of capacitor is great for filtering applications due to its small size and wide range of capacitances. The primary function of a film capacitor is to store electric charge which can be used to reduce noise and eliminate spikes in an electrical signal. This model also works as an energy reserve and provides a steady current over a period of time.

The working principle of a film capacitor is that when voltage is applied to its two terminals, an electric field is created within the capacitor. This electric field will cause the dielectric film to become polarized, which reduces the electric field. Since the electric field is automatically reduced in the presence of a polarized field, the capacitor holds a certain amount of electric charge and provides a steady current out of its terminals.

The BN074K0103K has a range of capacitances and voltages, making it suitable for many different applications. The low voltage rating and high capacitance make this model a great choice for an energy reserve, as it can filter and provide steady output current over a long period of time. Additionally, its axial package design makes it easy to mount or install in a variety of environments.
