Product details

1.5 µF at 10 V — decoupling and filtering fit

The TAJA155M010RNJ: This is a 1.5 µF molded tantalum chip rated at 10 V with ±20% tolerance, in the standard 1206 (3216 metric) footprint. The 10 Ohm ESR at 100 kHz sets the ripple current ceiling — for a 100 kHz buck converter output, the ripple voltage across this cap is ESR × ripple current, so a 100 mA ripple produces 1 V pk-pk. The 1206 case keeps the board footprint small, but the ESR is higher than a larger-case tantalum or a ceramic would deliver.

The 2000-hour endurance at 125°C is typical for tantalum; derate the voltage by 50% at the high end to stay within the reliability envelope.

No last-time-buy window, no successor to evaluate.

Frequently asked questions

Can TAJA155M010RNJ replace TAJA105M010RNJ on the same BOM line?

TAJA105M010RNJ is a 1 µF part in the same TAJ series, same 10 V rating and 1206 case. The 1.5 µF TAJA155M010RNJ is a drop-in replacement if the circuit can tolerate the higher capacitance — check the output ripple and loop stability in a regulator application, since the higher capacitance shifts the pole frequency.

Is TAJA155M010RNJ RoHS compliant?

The evidence does not list a RoHS compliance status. KYOCERA AVX typically marks RoHS compliance on the reel label and in the datasheet; confirm with the datasheet or request a certificate of compliance at quote time.
