The TAJS335K006SNJ: This is a general-purpose molded tantalum capacitor from the TAJ series, rated 3.3 µF at 6.3 V with ±10% tolerance. The 1206 case (3.20 mm x 1.60 mm footprint) is a standard size that matches many existing board layouts — if you've placed a 1206 tantalum before, this lands on the same pads. The 9 ohm ESR is typical for a general-purpose tantalum at this capacitance and voltage. It is not a low-ESR part — expect higher ripple heating than a polymer or low-ESR tantalum at the same capacitance.
This cap can sit in an avionics black box that sees -40°C cold soak or a downhole tool that hits 105°C ambient — no derating needed for the temperature alone. The molded construction keeps the case sealed against moisture ingress across that range.
Active lifecycle — no obsolescence flag for new BOMs
The product status is Active. KYOCERA AVX continues to run the TAJ series as a standard molded tantalum line.
