10 µF bulk decoupling with 300 mOhm ESR
The TPSC106K025H0300 is a 10 µF molded tantalum capacitor from the TPS series, rated at 25 V with a 300 mOhm ESR. A lower ESR means less voltage ripple for the same ripple current, so this part suits output filtering on a 12 V rail stepping down to 3.3 V where the ripple current is modest.
Wide temperature range for industrial use
The 25 V rated voltage provides a 2:1 derating margin on a 12 V rail, which is standard practice for tantalum capacitors to avoid surge failures during power-on transients.
