3.3 µF, 16 V, 5 Ω ESR — the loss budget for a bulk decoupling cap
The TAJA335M016HNJ is a molded tantalum capacitor from the TAJ series, rated 3.3 µF at 16 V with ±20% tolerance.
125°C endurance — where the 2000-hour rating matters
Lifetime is specified at 2000 hours at 125°C. For a power supply output cap in an industrial motor drive that sees 105°C ambient, the capacitor's core temperature will be higher still — the 2000-hour figure is the baseline for derating calculations, not a guarantee of field life.
Active production — no EOL concern for new designs
The 1206 (3216 Metric) case and A-size code are standard, so the part is widely sourced through distribution.
