GRM158C80G226ME01D

GRM158C80G226ME01D is a 22 µF ±20% X6S multilayer ceramic capacitor from Murata in a 0402 (1005 metric) case, rated 4 V DC — maximum capacitance in the smallest mainstream footprint for 1.x V point-of-load rails. Murata's dimensions are 1.0 x 0.5 mm with thickness 0.8 mm (+0/−0.1 mm); X6S holds ±22% across −55 °C to +105 °C, and Murata's PIM database lists this exact code with production status available. The final D is the phi-180 mm paper-tape reel at 8,000 pieces. The selection point is 22 µF in 0402 at a 4 V rating — read Murata's own application limit before designing in: the specification restricts this part to consumer equipment. Selection advice: at 4 V the part belongs on core and memory rails, not on a 3.3 V rail with transients; and the nominal 22 µF falls steeply under bias at these dimensions, so design against Murata's bias curves, not the headline value.
