The TPSD686K020R0070: The 70 mOhm ESR is the figure that governs ripple current handling and self-heating in power-supply output filtering — lower ESR means less I²R loss at the switching frequency.
D-case 2917 footprint and temperature range
The -55°C to 125°C operating range covers the full automotive and industrial temperature envelope — no derating required at 85°C ambient for the voltage rating, though tantalum derating guidelines recommend staying below 80% of rated voltage for best reliability.
