Rated for -55°C to 125°C operation, the TPSD477K004R0100 covers the full industrial temperature envelope and extends into the lower automotive under-hood band — the 125°C ceiling means it can sit near a hot processor or power stage without derating the voltage below 4 V.
The ESR is 100 mOhm at 100 kHz. This value determines the ripple current rating and the self-heating under AC load — a lower ESR means less power dissipated as heat in the capacitor, which is critical for output filtering in switching regulators where the capacitor sees the switching frequency ripple.
