100 µF, 10 V — the ESR is the real limiter
The TPSX107K010R0200: That ESR figure governs ripple current handling — at 100 kHz, the capacitor can sink roughly 1.1 A RMS before self-heating pushes the core temperature above the 125°C ceiling. The -55°C to +125°C operating range covers industrial and military-grade environments — the capacitor's leakage current rises with temperature, but the ESR stays stable across the band. At 125°C, derate the voltage to 2/3 of rated (6.7 V) per AVX application guidelines to stay within the safe operating area.
TPS series — molded, general-purpose, low-ESR
The TPS series is AVX's standard molded tantalum line — the X case code (7.3 x 4.3 x 1.5 mm) is the low-profile variant, sitting 0.059" (1.50 mm) above the board. It uses a conductive polymer cathode for lower ESR than standard MnO2 tantalums, which reduces output ripple in switching regulators and improves transient response. For applications that need tighter tolerance, AVX offers the TPS series in ±5% on select values — but for most power designs, ±10% is the standard fit.
