The JMK212BJ226KG-T: 22 µF at 6.3 V in an X5R dielectric — this is a bulk-decoupling or SMPS-output-filter capacitor sized for a low-voltage rail. The X5R rating guarantees capacitance within ±15% across the operating window from -55°C to 85°C, which matters for ripple filtering precision: any drift beyond that window directly changes the filter corner frequency. The ±10% tolerance defines the as-shipped capacitance band at 25 °C. For a calibration or measurement front-end, confirm whether the full tolerance stack — X5R temperature drift plus initial tolerance — stays within the circuit's ripple-budget allocation. A single-stage L-C filter built around this part will shift its -3 dB point by roughly 5% at room temperature and up to 15% at temperature extremes.
Package and board clearance
0805 (2.00 mm × 1.25 mm) body, maximum thickness 1.35 mm. The 1.35 mm ceiling is the controlling dimension for board-side clearance in a stacked-capacitor layout — confirm the neighboring component does not stress the capacitor during reflow or under mechanical vibration. Reel orientation matters for automated placement yield: the cavity orientation on the carrier tape must match the picker's nozzle axis. The base product number JMK212B ties this part to the wider M-series 0805 MLCC family — series-matched second sources may exist with the same footprint and voltage grade.
