Capacitance, voltage, and case size
The TAJA106K004R: 10 µF capacitance with ±10% tolerance at 4 V rated voltage — this is a bulk decoupling capacitor for a 3.3 V or lower rail where the derating margin is already baked into the 4 V rating. 1206 (3216 Metric) case, size code A, with a seated height of 1.80 mm max. The footprint is standard for reflow assembly; the low profile fits under a heatsink or on a tight backside PCB.
The molded construction handles the thermal expansion mismatch better than a conformal-coated chip.
