Film Capacitors

Film capacitors – 185684K50RFB-F – are part of a wide range of film capacitors available. These are non-polar, extremely miniature size electrolytic capacitors. They are used primarily in micro-electronic circuits, such as smart phones, tablets, computers and other digital equipment.

What is in a Film Capacitor?

Film capacitors fall into two categories – electrolytic and non-electrolytic. Electrolytic film capacitors incorporate a semipermeable membrane between the two electrodes, while non-electrolytic capacitors consist of a single sheet of metal foil material. Both types of capacitors provide high capacitance because of their construction. A combination of both types of film capacitors can be used for better performance and higher stability.

Application Field and Working Principle of 185684K50RFB-F

The 185684K50RFB-F is a non-polar, extremely miniature size electrolytic film capacitors – designed for use in micro-electronic circuits. These capacitors are known for their high capacitance values, low ESR, low stray capacitance, and fast discharge. The construction of the capacitor consists of a metallized polyethylene-terephthalate layer sandwiched between two plates. This type of capacitor allows for higher stability due to its low ESR.

The working principle of the 185684K50RFB-F is to charge and discharge electrical current. When connected to a power supply, the capacitor accumulates electric charges between the two plates until a certain voltage level has been reached. This voltage level is called the “threshold voltage”. When the threshold voltage is reached they become conducting and the electric current on the plates is discharged. The energy stored in the capacitor is then released and used by the circuit.

The 185684K50RFB-F is used in a number of applications such as electromechanical fields, regulated power supply units, direct current rate measurement, high frequency filtering, power control circuits, microcontrollers, and insulation/transient protection. These capacitors are also used for headphone audio and vibration motor drivers, chip sets of cell phones and other digital equipment.

Advantages of Film Capacitors

Film capacitors are designed to provide low ESR and long life at high temperatures and are very reliable. They are also known to have low dielectric loss and very low electrical noise. Due to their structure, they are used mainly when high stability is the primary requirement.

Another benefit of using a film capacitor is the fact that they require no special mounting requirements. Most of them are built to be placed and connected to the circuit directly without using any additional mounting hardware. This makes film capacitors very easy to use in a variety of applications.

Conclusion

Film capacitors are an essential part of modern electronic circuits and a wide range of them are available. The 185684K50RFB-F is a high quality, non-polar, extremely miniature size electrolytic film capacitor designed for micro-electronic circuits. Its robust construction and superior performance make it ideal for many applications. In addition, it requires no special mounting requirements and is easy to use.
