Molded tantalum for automotive bulk decoupling
The C-case (2312 / 6032 Metric) footprint is a common choice for output filtering on 5 V and 3.3 V rails in automotive modules, where the AEC-Q200 qualification (cite:) confirms it has passed the temperature cycling, moisture resistance, and mechanical shock tests required for under-hood and cabin deployment.
ESR and temperature range that set the operating margin
ESR is 1.2 Ohm at 100 kHz (cite:) — this is the self-heating term in ripple-current calculations. For a 100 kHz buck converter output, the ripple current squared times ESR gives the internal temperature rise; keep the sum of ambient and self-heating below 125 °C.
