Film capacitors are widely used in electric, electronic, communication and other digital devices. The 185274J63RCB-F type is one of the most typical types of fixed capacitors due to its many advantages. This article will introduce the application field and working principle of 185274J63RCB-F type film capacitors.

185274J63RCB-F type film capacitors are mainly applied in automobiles, audio/video equipment, notebooks, hard disk drives, digital cameras, modems, and electronic interfaces. They have good surge capacity and stability, low internal resistance, and high insulation resistance. Moisture resistance and flame retardancy grade significantly better than conventional aluminum electrolytic capacitors.

The structure of 185274J63RCB-F type film capacitors is composed of metalized polypropylene film, which is made of 65 nanometer thick metal film with high pure aluminum. This carrier layer is between an external aluminum foil layer and a di-electric layer. A needle is designed above the dielectric layer to protect it from mechanical damage.

The inner most layer of the capacitor is the dielectric layer. This is a layer of polypropylene film coated with a thin layer of aluminum. This provides a good path for electrical conduction between the central metal plate and the outer shield. The central metal plate is the terminal for power connection. The outer layer, or the exterior layer, is the shield which prevents the current from escaping.

The working principle of 185274J63RCB-F type film capacitors relies on two principles of physics: capacitance and resistance. When a power supply is applied to the central metal plate, electrical charge is stored on the dielectric layer and accumulated. This creates a voltage difference across the capacitor, resulting in an electric field. The resistance of the dielectric layer restricts the flow of current, while the capacitance determines how much electric charge can be stored. The electric field produced by the voltage difference is used to store and release charge, resulting in alternating current.

The advantages of 185274J63RCB-F type film capacitors are numerous. They are non-polarized, meaning that they can be connected in either direction. They are also lighter and smaller in size than other types of capacitors, making them more versatile for use in consumer electronics. Additionally, their price is much lower than other types of capacitors, making them an economical choice for many applications.

In conclusion, 185274J63RCB-F type film capacitors are widely used in a variety of applications due to their many advantages. Their working principle is based on the principles of capacitance and resistance, and their small size and low cost make them an ideal choice for many projects.
