1.5 µF, 10 V, 1206 — bulk decoupling for tight boards
The TAJS155K010RNJ is a molded tantalum capacitor from the TAJ series, rated at 1.5 µF with ±10% tolerance and a 10 V working voltage. It comes in a standard 1206 (3216 Metric) surface-mount package, measuring 3.20 mm x 1.60 mm with a seated height of 1.20 mm. With an ESR of 20 Ohms, this part is best suited for general-purpose bypass and filtering where moderate ripple current is expected, rather than high-frequency decoupling where lower ESR polymer caps would be preferred.
