Film Capacitors

Film capacitors are generally used as an alternative to electrolytic capacitors in circuits that require high voltage motor control to reduce electric noise. Film capacitors, also known as dielectric capacitors, are composed of non-coated and insulated metal foil layers with several layers of thin film/dielectric material. In comparison to other types of capacitors, the use of film capacitors can provide enhanced performance and cost-efficiency. The F17102151000 film capacitor is one type of film capacitor that is both cost-effective and efficient, providing greater electrical noise performance and greater power output.

Application Field of F17102151000

The F17102151000 capacitor is a high-voltage and ceramic film capacitor that is widely used in various electronics applications, such as motor controllers, power supplies, amplifiers, instrumentation, and digital circuits. These capacitors provide outstanding performance for high-voltage DC and AC applications, and they offer a long-term stable operation and good reliability. They are suitable for frequencies up to a few dozen kHz and can be used in a wide temperature range from -55°C to +105°C.

Moreover, the F17102151000 capacitor is resistant to electric shock, dust, humidity, and temperature, as well as for shock proof and vibration proof. The F17102151000 capacitor can also be used for various power line coupling filters, differential mode noise suppression filters, and interference immunity for inverters.

Working Principle of F17102151000

The working principle of the F17102151000 capacitor lies in its design and construction—the layers of thin film plastic or polyester serve as the dielectric material, while the super thin aluminum foil layers serve as the electrodes. The thin layers of aluminum foil form the capacitor’s “plates,” or electrodes, which are separated by a thin film of dielectric material. This is then tightly rolled up and sealed with varieties of non-conductive varnish.

The capacitance of F17102151000 occurs when a voltage is applied across the two electrodes, which causes a displacement of ions within the thin film dielectric material. This leads to the accumulation of electric charge on the capacitor’s plates, building up a potential energy. The field created is proportional to the amount of charge, developing the capacitors electrical capacitance, which is measured in Farads. When the voltage is removed, the ions are free to move, and the built-up charge is dissipated, depleting the capacitors’ potential energy.

Conclusion

The F17102151000 film capacitor is one of the most widely used film capacitors due to its cost-effectiveness and performance. The F17102151000 capacitor is a high-voltage and ceramic film capacitor that is widely used for various electronics applications, such as motor controllers, power supplies, amplifiers, and digital circuits. Its working principle is based on the layers of thin film plastic or polyester serving as the dielectric material, while the super thin aluminum foil layers serve as the electrodes.
