Product details

15 µF, 20 V molded tantalum for tight board budgets

The TAJB156M020RNJ is a 15 µF, 20 V molded tantalum capacitor in the TAJ series from KYOCERA AVX, housed in a 1411 (3528 Metric) surface-mount package with ±20% tolerance. With a 2 Ohm ESR rating, this part handles moderate ripple currents typical of decoupling and bulk storage roles on 12 V and 5 V rails.

Surface-mount footprint and temperature grade

The 1411 (3528 Metric) case measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm, fitting standard reflow profiles for tantalum capacitors.

Frequently asked questions

Can I use a tantalum capacitor to replace an aluminum electrolytic?

Tantalum capacitors offer lower ESR and better stability over temperature than aluminum electrolytics of similar capacitance, but they are voltage-sensitive and can fail short if reverse-biased or subjected to high inrush current. For a 15 µF, 20 V decoupling role, a tantalum is a direct replacement if the circuit can tolerate the lower ESR and the voltage derating guidelines are followed.
