The TPSD476K010R0100: The 100 mOhm ESR keeps ripple heating manageable in output filtering and hold-up circuits — for a 1 A step load at 500 kHz, the self-heating stays under 5 °C above ambient. The molded case resists mechanical stress during pick-and-place and reflow, reducing the risk of internal anode damage common in uncoated chips.
Wide temperature range and ESR for industrial and automotive
Rated -55 °C to 125 °C, this cap operates across the full industrial and under-hood automotive temperature envelope. The 100 mOhm ESR is specified at 25 °C and 100 kHz — expect ESR to rise roughly 2× at -55 °C and drop to ~60 mOhm at 125 °C, per typical tantalum behavior. Budget the cold-ESR increase when sizing ripple current at low temperature. The ±10% tolerance is tight enough for most bulk decoupling and energy-storage roles.
