Working Principle

The SMC5.7473J50J33TR12 film capacitor operates on the principle of electrostatic attraction. When a voltage is applied across the capacitor, positive and negative charges accumulate on each of the capacitor\'s separated plates. At the same time, an electric field is created between the plates. The magnitude of the electric field is proportional to the applied voltage and is further determined by the total capacitance of the device.

The amount of capacitance, or capacitive reactance, of the SMC5.7473J50J33TR12 is determined by the capacitance construction of the device. It has a thin layer of film, such as polypropylene or film foil, sandwiched between two conductive layers. As the applied voltage increases, the conductive layers draw closer together, creating a smaller separation distance and thus a higher capacitance. This is referred to as a capacitance voltage rating, and is expressed as a ratio of the applied voltage to the capacitance.

In terms of performance characteristics, the SMC5.7473J50J33TR12 is a low-loss, low-profile capacitor rated for high temperature operation. It offers excellent high frequency response and low self-inductance, making it well suited for high-frequency applications. It also has an excellent self-healing capability, allowing it to automatically recover from shorted conditions.
