470 µF, 6.3 V, 45 mOhm ESR — bulk decoupling in the D case
The TPSD477M006R0045: That ESR figure is the number to watch in power-supply decoupling and hold-up circuits: at 470 µF and 6.3 V, the 45 mOhm ESR limits ripple voltage and self-heating, so this part handles higher ripple current than a standard tantalum with similar capacitance but twice the ESR would. The molded construction gives consistent dimensional control during reflow and simplifies pick-and-place handling.
Temperature range and operating environment
At the high end, the voltage derating curve applies — standard practice for tantalum capacitors is to apply 50% de-rating (3.15 V max in this case) for best reliability, especially in circuits with low-impedance sources. General-purpose feature set (no low-ESR or high-reliability suffix) means it fits bulk decoupling and filtering roles where the 45 mOhm ESR is acceptable and the operating temperature stays within the -55°C to +125°C window.
