The TAJB685K020SNJ: This is a surface-mount molded tantalum capacitor from the TAJ series, rated 6.8 µF at 20 V with a ±10% tolerance. The B case (1411 / 3528 Metric) measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm, fitting a standard 1210 footprint.
The molded construction provides mechanical protection and moisture resistance better than uncoated chips.
The two parts share the same TAJ series, B case, 6.8 µF capacitance, and ±10% tolerance. TAJB685K020SNJ is rated at 20 V, while TAJB685K016SNJ is rated at 16 V. The 20 V part can replace the 16 V part in the same footprint as long as the voltage derating guidelines for tantalum capacitors are observed — typically 50 % derating on applied voltage.
