The capacitors are a type of passive electronic component, specifically a capacitor with an electrolyte and dielectric material that stores energy in the form of electric charge. A ceramic capacitor is one type of capacitor made from ceramic materials, which have a stable capacitance over temperature ranges. This specific capacitor, VJ0805Y474MXJRW1BC, has a capacitance value of 0.47 microfarads and can withstand voltages up to 16 volts. It follows the X7R classification, indicating it has a relatively stable capacitance within a certain temperature range. The capacitor is designed for use in various electronic applications, including filters, resonant circuits, and other devices where small capacitance values are necessary.
