The specified capacitor is a type of ceramic capacitor with the following characteristics: it has a capacitance of 0.22 microfarads, a tolerance of ±20%, and a maximum operating voltage of 25 volts. Its case size is designated as 1210 or 3225 metric. It utilizes an X7R dielectric material, which is a type of ceramic used in capacitors that exhibits stable capacitance over a broad range of frequencies but also has some temperature coefficient to its value.
