Bulk decoupling for 3.3 V to 12 V rails
The TPSV107K025R0100: This capacitance and voltage combination fits bulk decoupling on power rails from 3.3 V up to 12 V, where the 25 V rating provides margin against transients without oversizing the case.
ESR and ripple current trade-off
With 100 mOhm ESR at 100 kHz, this capacitor sits in the moderate range for a 100 µF tantalum in a 2924 case. The ESR directly limits ripple current handling — at 25 V and 85°C ambient, the self-heating from ripple current stays within the 125°C max rating as long as the RMS current stays under the derated limit. For low-ESR applications like output filtering on a switching regulator, a polymer or multi-layer ceramic cap would be a better fit; this part is aimed at bulk storage where ESR is secondary to capacitance density.
Temperature range and board placement
The -55°C to 125°C operating range covers industrial control, telecom outdoor cabinets, and under-hood automotive electronics without derating. The 2924 (7361 Metric) case — 7.30 mm x 6.10 mm footprint with 3.75 mm seated height — uses a standard land pattern compatible with reflow soldering. The molded case provides mechanical protection during pick-and-place and resists cracking from board flex, a common failure mode for conformally-coated tantalums.
