A 22 pF (Pico Farad) multilayer ceramic capacitor great for use with crystal oscillator operation. Other specifications include: voltage rating 200 V, tolerance 5% and operating temperature range of -55 degree C to 125 degree C.
These capacitors are typically used with crystals to insure proper function of the crystal. A crystal will have a specified capacitance and this is calculated along with the capacitance on the PCB to derive the proper value for the capacitor.
