47 µF at 10 V — ESR drives the derating decision
The TPSW476M010R0150: The ESR figure sets the ripple-current ceiling — at 150 mOhm, the self-heating at rated ripple is manageable for bulk decoupling on a 10 V rail, but derating the applied voltage by 20 % (to 8 V) is standard practice for tantalum reliability in power-supply and filter circuits.
Case size and temperature range
The operating temperature range of -55°C to 125°C covers automotive under-hood and industrial extended-temperature environments without requiring a high-temperature derating curve beyond the standard voltage derating.
