The FM21X222K251PXG is a surface mount multilayer ceramic capacitor (MLCC) with a capacitance of 2.2 nanofarads (nF), a maximum operating voltage (V) of 250 volts, and an 0805 (2032 metric) footprint. It is manufactured by Prosperity and is RoHS (Restriction of Hazardous Substances) compliant. The capacitor features a high stability over a wide temperature range, low equivalent series resistance, and a small form-factor for high-density circuit board designs. This MLCC can be used for many different applications, including bypass, filtering, decoupling, blocking, and timing.
