4.7 µF, 35 V, 1.5 Ω ESR — military-temp molded tantalum
The TPSB475M035R1500 is a molded tantalum capacitor from KYOCERA AVX's TPS series, rated at 4.7 µF with a 35 V working voltage and ±20% tolerance. The 1.5 Ω ESR at 100 kHz sets the ripple current handling and self-heating ceiling — for a 35 V rail decoupling, the ESR limits the voltage ripple to a few tens of millivolts at moderate ripple currents.
Rated for -55 to 125 °C, this capacitor covers the full military temperature band — suitable for avionics, downhole instrumentation, and satellite power buses where the ambient swings from cold-soak to hot-soak without derating the voltage below 35 V.
