10 µF, 16 V molded tantalum — TAJ series
Rated ±10% tolerance, the part delivers a predictable capacitance window for timing or ripple-sensitive circuits where tighter control is needed than the standard ±20% grade.
Temperature range and lifetime — full military band
The rated lifetime is 2000 hours at 125°C, meaning the capacitor is derated for continuous high-temperature exposure; in a 85°C environment the effective life extends well beyond that figure per the Arrhenius acceleration typical of MnO2 tantalum technology.
ESR and frequency — what 2 Ohm at 100 kHz means
Equivalent series resistance is specified at 2 Ohm measured at 100 kHz — this is the impedance floor for ripple current in a switching converter output or a local decoupling node. A higher ESR than polymer or ceramic alternatives means the capacitor self-heats more under ripple, so the ripple current rating should be checked against the application's AC load.
Package and footprint — 2312 case, size C
Housed in the 2312 (6032 Metric) surface-mount case, size code C, the capacitor measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm max — a common footprint for 10 µF tantalums in the 16 V class, compatible with standard reflow profiles.
