10 µF, 10 V, 1 Ohm ESR — the ESR drives the ripple-current budget
The TPST106K010R1000: That ESR figure is the limiting factor for ripple current handling — at a given ambient temperature, the I²R self-heating must stay within the part's power dissipation rating to avoid derating or premature failure. For a typical 100 kHz buck converter output, this ESR contributes about 10 mV of ripple voltage per amp of load step, which is acceptable for many general-purpose decoupling and bulk storage roles. The ±10% tolerance is standard for tantalum electrolytics and suits filtering and decoupling where the exact capacitance value is not critical. The molded case provides consistent dimensions for pick-and-place and good mechanical stability on the board.
Active lifecycle — no last-time-buy scramble needed
That means the manufacturer continues to produce it, and there is no imminent end-of-life notice. For a BOM line that uses this capacitor, you can plan normal replenishment cycles without worrying about a last-time-buy window closing. The part is supplied in Tape & Reel packaging, which is the standard format for automated surface-mount assembly. The 1411 (3528 Metric) / 1210 case size is a common footprint, so board layout reuse across multiple capacitor values in the same family is straightforward.
Temperature range and board-fit
This covers industrial control cabinets, automotive under-hood electronics, and outdoor telecom equipment. The 125°C upper limit means the capacitor can sit near a hot power supply or motor drive without derating the voltage rating — though the ripple current must still be derated per the manufacturer's curve above 85°C. The seated height is 1.40 mm max, which fits low-profile designs such as blade servers, compact PLC modules, and handheld instruments.
