The TAJA475K016SNJ: Rated 4.7 µF at 16 V with ±10% tolerance, this molded tantalum capacitor fits decoupling and filtering roles on a 12 V or 5 V rail where the applied voltage stays below 80% of the 16 V rating for derating margin.
Housed in a 1206 (3216 Metric) case, size code A, with dimensions 3.20 mm x 1.60 mm and a seated height of 1.80 mm. The molded construction provides mechanical stability and moisture resistance during reflow.
The suffix difference (SNJ vs RNJ) typically indicates a packaging or termination finish variant. Both share the same 4.7 µF, 16 V, ±10%, 1206 footprint and TAJ series. Confirm the termination finish and RoHS status of RNJ against your assembly process before substituting.
The evidence does not list a RoHS compliance status for this order code. Check the manufacturer's datasheet or contact KYOCERA AVX directly for the current RoHS declaration.
The 1206 (3216 Metric) case measures 3.20 mm x 1.60 mm with a seated height of 1.80 mm. Standard 1206 solder pad layout applies; no special via-in-pad or thermal pad is required.
No — TAJA475K016SNJ is rated 16 V. Substituting a 10 V capacitor on a rail that sees transients above 10 V risks dielectric breakdown and short-circuit failure. Always derate tantalum capacitors to at least 80% of rated voltage.
