It is generally used in transformers, ballast, motors, lamps, computers, and audio/video systems. The capacitor can be also found in ignition circuits, pulse circuits, lights, timers, and meters.

The capacitor can be availed in various dimensions, depending on the model and its application. The available size for the 947C471K102CDI is 9mm×7mm×27mm. The capacitor is also equipped with a small creepage distance making it ideal for space constrained applications. It has a rated operating temperature of -40℃ to +85℃.

Working Principle of 947C471K102CDI

The 947C471K102CDI consists of two electrical plates, separated by a thin dielectric film. It is a static device, meaning that the capacitance does not vary over time. Ideally, the capacitance remains constant, while the resistance, or impedance, varies as a function of frequency. This is known as the capacitive reactance. The reactance is determined by the charge stored in the capacitor.

The 947C471K102CDI works like a tiny energy reservoir. Whenever an electric field is generated, the capacitor starts accumulating a charge. The energy stored in the capacitor is then released, allowing electrical current to pass through. The capacitor works similarly in reverse, absorbing energy when the electric field is reduced. As the charge stored in the capacitor decreases, its capacitance also reduces.

The capacitor also works as a high-pass filter. It allows higher frequency components of a signal to pass through while attenuating the lower frequency components. That is why it is generally used in audio applications, such as filters and amplifiers. The capacitor can also be used to change the phase of a signal, allowing a signal to be shifted in time.

The 947C471K102CDI has a self-healing dielectric which mends any damage caused by voltages spikes or other corrosive agents. It is extremely reliable and can last for up to 10 years. The capacitor is also eco-friendly and RoHS compliant, which means that it does not release any hazardous materials into the environment.
