The TPSE227K010H0050: Its 50 mOhm equivalent series resistance (ESR) at 100 kHz is the load-bearing spec for ripple current handling in power-supply output filters — lower ESR means less self-heating and better voltage regulation under AC load.
Temperature range and deployment context
Rated for -55°C to +125°C operation, this capacitor is suited for environments spanning cold-start automotive electronics to hot-side industrial power stages — the wide range covers most non-avionics, non-radiation-hardened applications. The TPS series is characterized as a general-purpose tantalum line, so it lacks the surge-current or low-ESR screening of dedicated automotive or high-reliability families — evaluate the 50 mOhm ESR against the ripple current in your specific circuit before committing the BOM line.
