330 µF, 10 V — bulk tantalum for rail decoupling and hold-up
The TPSD337K010R0100: The 100 mOhm ESR is the dominant loss term at ripple frequency — it sets the self-heating and ripple voltage the capacitor sees under load, so the actual ripple current capability is ESR-limited, not just capacitance-limited. The -55°C to 125°C operating range covers the full military temperature grade, making this part viable for avionics, downhole instrumentation, or engine-bay electronics where the ambient exceeds the commercial 85°C ceiling.
D-case footprint and board-fit constraints
The pad geometry on the PCB must match the manufacturer's recommended land pattern to keep the solder joint stress within limits during thermal cycling; a smaller pad increases the risk of tombstoning or corner cracking. Cut Tape is typical for prototyping or low-volume builds; Tape & Reel feeds directly into a reel-to-reel placement machine.
