Active production — automotive-grade tantalum for 12 V rails
The KYOCERA AVX TAJA335M016TNJ is a molded tantalum chip capacitor in the TAJ series, rated 3.3 µF at 16 V with ±20% tolerance. The 1206 case is a common footprint for bulk decoupling near microcontrollers or sensors in engine control units and body controllers.
Key ratings for BOM fit
ESR is 5 Ω at 100 kHz — this is the effective series resistance that governs ripple current handling and self-heating. For a 3.3 µF decoupling cap on a 16 V rail, the ESR is moderate; derate the ripple current if the ambient exceeds 85°C. Lifetime is specified at 2000 hours at 125°C — the rated endurance under full voltage and temperature. In a 105°C engine bay, the expected life roughly doubles per 10°C drop below the rated temperature, giving a practical margin for most automotive duty cycles.
