Capacitance, voltage, and case size for BOM fit
TAJC107M010K is a molded tantalum capacitor from the TAJ series, rated at 100 µF capacitance with a 10 V voltage rating and ±20% tolerance — the standard decoupling and bulk-storage value for 3.3 V and 5 V rails in portable and industrial designs. The 2312 (6032 Metric) case measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm, fitting the C-size footprint common on mixed-signal boards where board space is allocated per the manufacturer's land pattern.
Temperature range and ESR for harsh environments
The 1.2 Ohm ESR at 100 kHz sets the ripple current capability and self-heating floor — for a 100 µF output capacitor on a 500 mA buck converter, the ESR contributes roughly 60 mV of output ripple, which is within the tolerance of most 3.3 V logic supplies.
