220 µF, 10 V, 100 mOhm ESR — bulk decoupling for a 10 V rail
The TPSE227K010R0100V: Its 100 mOhm equivalent series resistance (ESR) at 100 kHz keeps ripple heating low in switching-regulator output filters and point-of-load decoupling — the ESR figure is the one that governs the capacitor's self-heating and ripple-current capability, not the capacitance alone.
125°C endurance and operating range
The molded case construction provides mechanical stability and moisture resistance during reflow assembly, though the 2000-hour endurance figure at maximum temperature should be derated for applications requiring continuous operation beyond that window.
