Film Capacitors

Film capacitors are a type of non-electrolytic capacitor which are designed using dielectric thin films, such as polyester, polypropylene, polystyrene, teflon or mylar. They are composed of two metal foils, each of which is separated by a thin layer of dielectric material. The main advantages of film capacitors are that they provide excellent electrical properties, such as low capacitance drift with temperature and voltage, good dielectric absorption, low source inductance, high frequency stability and low ESR. This makes them well suited for high frequency, high accuracy and low EMI applications.

B32537B1105K Application Field and Working Principle

The B32537B1105K film capacitor is a non-electrolytic axial-leaded polyester capacitor designed for general purpose applications. The B32537B1105K is a high temperature rated radial leaded polyester film capacitor. It has a capacitance of 0.47 μF, a working voltage of 400 VAC and a capacitor tolerance of ±10%. This capacitor is excellent for high accuracy, high frequency, and low EMI applications. Its performance characteristics include low temperature drift, good dielectric absorption, and low source inductance.

The B32537B1105K is a two-terminal device, consisting of two metal foils separated by a dielectric thin film. When a voltage is applied to the capacitor, electrostatic attraction occurs between the two metal foils, causing a charge to accumulate on the capacitor. This charge stored on the capacitor produces an electric current in the circuit, and thus enables it to act as a filter in electronic circuits. In a capacitor the addition of charges to the plates creates an electric field in the dielectric material. This electric field creates a restoring force that opposes the applied charge and thus stores energy in the capacitor.

The B32537B1105K is designed for general purpose applications such as sensing circuits, inverters, power supplies, oscillators, timers, and filters. It can be used for AC applications where arc suppression is required, and also in switching power supplies where snubber circuits are required. The B32537B1105K is also well suited for use in high voltage motor circuits, air conditioning, audio amplifiers, and DC-DC converters. It is also suitable for use in high voltage applications such as switch modes, as well as in high frequency pulsed applications where inductive loading is present.

In conclusion, the B32537B1105K is a high temperature rated radial leaded polyester film capacitor designed for general purpose applications. It provides excellent electrical properties, such as low capacitance drift, good dielectric absorption, low source inductance, high frequency stability and low ESR, making it well suited for high accuracy, high frequency, and low EMI applications.
