68 µF, 16 V, 70 mOhm ESR — the ESR is the load-bearing spec
The TPSD686K016R0070: The 70 mOhm equivalent series resistance (ESR) is the spec that governs ripple current handling in a power rail — lower ESR means less self-heating and better filtering at switching frequencies. Housed in the 2917 (7343 Metric) D case, it fits the standard footprint for high-density surface-mount designs. The operating range from -55 to 125 °C covers industrial enclosures and under-hood automotive ambient without derating at the high end.
