Film Capacitors

Film capacitors are non-polar capacitors created from films, such as plastic films, and have great characteristics like high capacitance, small physical size, very low reactance and equally low absorption. Polystyrene introduced the concept of film capacitors in the market in 1951 and they have been used in almost every industry ever since.

185223K250RCB-F Application Field

The 185223K250RCB-F is a polystyrene film capacitor. It is particularly suitable for pulse and high frequency applications. It is commonly used in appliances, automation equipment, consumer electronics, medical devices, power supplies, and robotics.

185223K250RCB-F Working Principle

A film capacitor consists of two metal plates that are separated by a thin layer of plastic film. When a voltage is applied, the positive charge attracts the negative charge and stores the charge. Since there is no chemical reaction in a film capacitor, the charge is retained for a much longer period of time than in a regular capacitor. This makes the film capacitor ideal for high frequency applications as it can handle large amounts of electrical pulses.

The 185223K250RCB-F capacitor uses polystyrene film for its dielectric. The two plates are connected via wires and the plastic film serves as the insulator. It has a maximum exposure temperature of 70°C, making it suitable for continuous operation. The capacitor also has a low ESR, making it ideal for high frequency applications where low inductance is desired.

The maximum working voltage for the 185223K250RCB-F capacitor is 250V DC, which is sufficient for most applications. It also has a capacitance of 0.022 micro Faraday, which is relatively high for a capacitor of its size. The combination of its low ESR and its high capacitance makes it an ideal choice for applications where a fast response is required.

Conclusion

Film capacitors offer a variety of advantages over other types of capacitors. They are smaller in size, have higher capacitance, are much more tolerant of temperature fluctuations, and have low reactance and absorption. The 185223K250RCB-F is a polystyrene film capacitor that is perfect for high frequency applications due to its low ESR and high capacitance. It has a maximum working voltage of 250V DC and can be used safely in applications with temperatures up to 70°C.
