Film capacitors are a type of capacitors that are used mainly in digital electronic circuits. These capacitors are made up of thin film of plastic or paper that is coated with a conductive material such as metal or aluminum. The films are then connected to two metal plates to form a capacitor. The purpose of a film capacitor is to store a charge when a voltage is applied to it, and then to discharge that charge when the voltage is removed. The capacitance of a film capacitor is determined by the amount of charge that can be stored in its dielectric layer.The F339X136848KI02W0 is a type of film capacitor that is designed for use in high frequency, low ripple signal transmission, anti-surge rectification, and power source filtering applications. It has a cylindrical design and is composed of an insulating dielectric film, a conductive coating, and two terminals. The capacitance of this device is 4.5uF and it has a voltage rating of 400V. Its maximum operating temperature is 105°C and its tolerance is +/-20%.The working principle of the F339X136848KI02W0 is based on the fact that when a voltage is applied across its terminals, an electric field is created in the dielectric film, causing the positive and negative charges to be attracted to the opposite surfaces of the dielectric. This creates a capacitive effect, allowing the capacitor to store an electric charge. When the voltage is removed, the electric field collapses and the stored charge is released.The F339X136848KI02W0 is mainly used in applications such as rectification, power source filtering, and high frequency signal transmission. It is capable of handling high voltages, and its wide operating temperature range makes it suitable for applications in extreme environmental conditions. It is also capable of handling sudden surge currents and offers good noise immunity. The device is also suitable for long-term storage applications, as it can maintain its capacitance and voltage rating over time.In conclusion, the F339X136848KI02W0 is a film capacitor that is designed for use in applications such as rectification, power source filtering, and high frequency signal transmission. It is composed of an insulating dielectric film, a conductive coating, and two terminals, and its capacitance is 4.5uF. It can handle high voltages and extreme temperature ranges, and is suitable for long-term storage applications.
