What this tantalum capacitor delivers for a power rail
The TPSE106M050R0250: This ESR figure is the key selection parameter for a bulk decoupling or hold-up cap on a 48 V or 24 V bus — it limits ripple voltage and self-heating under AC load, so the capacitor runs cooler in a power supply output stage.
Fit and footprint for the board layout
The manufacturer size code E means this is the physically larger case in the TPS family — it handles the 50 V rating and the low ESR without the derating penalty a smaller case would impose. Surface-mount assembly with a ±20% tolerance on the 10 µF value — typical for tantalum bulk capacitors, where the capacitance drift with temperature and DC bias is already accounted for in the selection margin.
Temperature grade and environment
In a power supply sitting next to a hot MOSFET or a regulator in an enclosed chassis, the 125°C ceiling gives margin before derating starts.
