The TPSY686K016R0250: That ESR figure is the one that matters for ripple handling — a lower ESR means less self-heating and better filtering on a switching regulator output. The ±10% tolerance is standard for tantalum electrolytics in this class; plan for the actual capacitance to sit between 61.2 µF and 74.8 µF at 25 °C. Voltage derating to 10 V or less is a good practice to improve reliability on a 16 V-rated part.
The molded case provides mechanical protection and consistent pad geometry for soldering. Tape & Reel packaging means it ships ready for automated assembly without manual handling.
Active lifecycle — no end-of-life watch needed
Because it is an active standard-series tantalum, the supply channel is stable.
