Film Capacitors

Film capacitors are components used for storing energy, filtering out electromagnetic interference, controlling current impulses, and blocking DC voltage. A 150394K63CB is a type of capacitor made from polyethylene-terephthalate (PET) film. It is a surface-mounted, snap-in style capacitor with a voltage rating of 500Vac and a capacitance value of 0.0047µF.

Application Field

Film capacitors are extremely versatile, multi-purpose components and used in a variety of industrial and consumer electrical applications. The 150394K63CB capacitor is designed for X-ray machines, medical equipment, and power supplies, where constant performance is essential. It can also be used as a signal-conditioning component and EMI/RFI filters.

Consumer Electronics

Consumer electronics such as TVs, DVD players, video game consoles, sound systems, and other home entertainment devices commonly require film capacitors for proper voltage and current regulation. The 150394K63CB capacitor can be used as a filter for DC and AC signals, providing both protection and signal accuracy to the device.

Industrial Applications

Film capacitors are often used in industrial applications where vibration, temperature fluctuation, or high loads are factors. The 150394K63CB capacitor is suitable for industrial applications due to its low ESR (equivalent series resistance) and high operating temperature range. It is often incorporated into motor drives, air conditioning systems, and power supplies.

Working Principle

Film capacitors use an alternating electric field applied to insulating polymer film to store energy. The 150394K63CB capacitor is constructed with two electrodes attached to a rectangular polymer film. When power was applied to the capacitor, the electric field induces an electric charge on the surface of the dielectric material. This is what gives the capacitor its capacitance and allows it to store and release energy when needed. When connected in a circuit, the capacitor will begin to store charge on its electrodes. The charge accumulates more rapidly when a higher voltage is applied or when the capacitor is connected to a larger circuit. The charge continues to accumulate until the voltage across its terminals reaches the rated voltage. At this point, the capacitor has reached its maximum charge and cannot store any more charge. When the circuit is disconnected, the accumulated charge will slowly dissipate over time.

Conclusion

The 150394K63CB capacitor is a versatile, multi-purpose component designed to provide voltage and current regulation in a variety of industrial and consumer electrical applications. It can also be used for signal conditioning and EMI filtering. The capacitor operates using an alternating electric field applied to insulating polymer film to store energy. The charge accumulates rapidly when a higher voltage is applied or when the capacitor is connected to a larger circuit. When the circuit is disconnected, the accumulated charge will slowly dissipate over time.
