X2 Series AC Box Type Capacitor is a type of capacitor designed for use in AC circuits. These capacitors are classified as safety capacitors because they are specifically designed to meet safety standards and regulations for use in electronic devices and appliances that are connected to the AC power supply. These are made using a thin film of polypropylene as the dielectric material, which is coated with a thin layer of metal on both sides to serve as the electrodes. X2 Series AC Box Type Capacitor can be used safely in a wide range of electronic devices and appliances, including power supplies, lighting fixtures, and motor drives.
