B32921C3103M189 Capacitors

Film Capacitors

A Film Capacitor is a passive electronic component capable of storing electrical energy. It usually takes the form of a flat plastic film sandwiched between two metal plates. It is more rugged and efficient than the conventional paper capacitors. Film capacitors are described in terms of its type, dielectric material and various other physical characteristics such as rated voltage, maximum operating temperature range, dielectric strength and dissipation factor.

The B32921C3103M189 is one of the types of film capacitors. It is an electrolytic capacitor with aluminum anode and cathode, separated by a dielectric of Organic Polymer Film. This type of capacitor offers a high capacitance range and guarantees a long operating life even at extreme temperatures. The rated voltage of this type of capacitor is 35V and works in the temperature range of 6K-85K. It is capable of withstanding a high dielectric strength of 4KV at a frequency range of 100Hz.

The main application of the B32921C3103M189 is for signal filtering, smoothing and blocking DC components carried in high frequency AC signals. It is also used for smoothing supply voltages for low-power switching regulators. This type of capacitor is most commonly used in radio frequency and audio frequency applications, such as in car audio systems and home theatre amplifiers.

The working principle of the B32921C3103M189 follows the principle of electro-striction between the two electrodes. When a voltage is applied between the two electrodes, an electrostatic field is induced in the thin dielectric film and this induces a deformation in the film. This deformation creates a physical barrier in the form of an electro-striction force, which is what capacitive action is all about. The dielectric film acts as a barrier between the two electrodes, which prevents the flow of electrons, thus creating the capacitive action.

In conclusion, the B32921C3103M189 is a type of film capacitor that is used for signal filtering, smoothing and blocking DC components carried in high frequency AC signals. The working principle of this type of capacitor follows the principle of electro-striction between the two electrodes, where a physical barrier is created by the electro-striction force. It offers a high capacitance range and guarantees a long operating life even at extreme temperatures.
