The TAJB107M006RNJ is a surface-mount molded tantalum capacitor from the TAJ series, offering 100 µF capacitance at 6.3 V with ±20% tolerance. The 1.7 Ohm ESR sets the ripple current ceiling — for a 100 kHz buck converter output, the self-heating stays manageable, but the ESR floor means the output ripple voltage is roughly 170 mV per ampere of ripple current, which matters for a 1.2 V core rail where the allowed ripple is 30 mV. The -55 to 125 °C range covers avionics and downhole equipment; a 105 °C ambient with full rated voltage requires no derating, but at 125 °C the voltage derating curve in the datasheet should be followed.
