Film Capacitors

A film capacitor is a type of capacitor that uses a thin plastic film as its dielectric material. These capacitors are commonly used in various industrial, power electronics and audio/video applications, often due to their low loss factor, low impedance and good insulation properties. The most common type of film capacitor is the metalized polyester film, often referred to as Metallized Polyester Capacitors or Polyester Film Capacitors. Other types of film capacitors include paper/film, polypropylene and aluminum electrolytic, to name just a few.

B32912A5473M000 is an example of a film capacitor. It is a metalized polyester capacitor with a capacitance of 4.7uF and a voltage rating of 50Vdc. It is also known as a bipolar capacitor as it can be used in both positive and negative applications.

Application Field

The application field for B32912A5473M000 are very wide, as metalized polyester film capacitors are used in a variety of different applications. These include:

• Power electronics
• Audio/Video equipment
• Telecommunication equipment
• Security systems
• Automotive electronics

These capacitors are also used in radio systems, modulation systems, measuring and control instrumentation, medical equipment, personal electronic devices and much more.

Working Principle

The working principle of a film capacitor is quite straightforward. It consists of two conductive plates, separated by a thin dielectric material. When a voltage is applied to the capacitor, an electric field is created between the two plates. This causes the plate to be charged and creates a capacitance. The amount of capacitance is determined by the size of the plates and the thickness and permittivity of the dielectric material.

As the voltage increases, the capacitance increases as well. This is due to the fact that the electric field between the plates also increases, causing the plates to become increasingly more charged. The capacitance then reaches its peak value, known as the breakdown voltage.

The B32912A5473M000 is designed for a maximum operating voltage of 50Vdc, meaning that it can safely handle up to 50Vdc before it reaches its breakdown voltage.
