Film capacitors are an important type of capacitor that is designed with an insulation film as the medium between two electrodes. They provide electrical isolation and can increase the range of capacitance of the device. The 947D471K132CLRSN is a film capacitor developed by American company, Cornell Dubilier. It is a bipolar capacitor and is designed to operate in a range of temperatures and frequencies up to 50kHz.

Film capacitors are widely used in applications such as audio coupling, power supply bypassing, voltage shaping, and signal filtering. These applications are possible due to the high capacitance values over a range of temperatures, the low-loss behaviors and the high voltage breakdown characteristics of film capacitors.

Working Principle

The 947D471K132CLRSN is a bipolar electrolytic capacitor that uses thin film layers of glass, polypropylene, and tin foil to separate two metal plates. When a voltage is applied to the metal plates, electrons will flow from one plate to the other. This creates a surface charge on each plate, which will accumulate until it is discharged during the depletion phase. During the recharge phase, electrons will flow back to the opposite plate and a charge will accumulate until the full voltage is reached.

Film capacitors are ideal for suppression of electrical noise, filtering out spikes, and decoupling, due to their low inductance and the stability of the dielectric. The 947D471K132CLRSN is composed of a tin-plated foil and sheet for the anode, and a layer of polypropylene for the cathode. This design allows for excellent performance when operating in a harsh environment.

Film capacitors have excellent heat-dissipation properties as well, which makes them an ideal candidate for power factor correction. They are constructed so that the current flows from one plate to the other in a very linear way, allowing the capacitor to dissipate heat very quickly. This makes them ideal for applications where power dissipation needs to be minimized.

Advantages of 947D471K132CLRSN

The 947D471K132CLRSN provides excellent capacitance values over a range of temperatures, low-loss behaviors, and high-voltage breakdown characteristics.
