Product details

0.68 µF 35 V molded tantalum — fit for a 24 V rail with headroom

The TAJP684K035RNJ is a 0.68 µF, 35 V rated tantalum capacitor in the TAJ series from KYOCERA AVX, molded case, with ±10% tolerance and 13 Ohm ESR. The 35 V rating gives 46% margin over a nominal 24 V supply, which covers typical 24 V transients up to 30 V without exceeding the derating guideline (50% margin recommended for tantalum). The 0805 (2012 Metric) footprint is standard for low-profile decoupling or timing circuits on mixed-signal boards. The P case code (2.05 mm × 1.35 mm × 1.50 mm max height) fits under low-clearance components or shielding cans.

No special bake or moisture sensitivity level is listed, but as with all tantalum capacitors, the voltage derating guideline (50% of rated voltage) should be followed for best reliability.

Product status is Active from KYOCERA AVX.

Frequently asked questions

Can TAJP684K035RNJ be used in a 24 V circuit?

Yes. The 35 V rating provides 46% margin over a nominal 24 V rail, which meets the typical 50% derating guideline for tantalum capacitors. For best reliability, keep the applied voltage at or below 17.5 V (50% derating).

What is the ESR of TAJP684K035RNJ and why does it matter?

The equivalent series resistance is 13 Ohm. This is relatively high for a 0.68 µF tantalum; it limits the ripple current capability and increases self-heating. The part is better suited for decoupling or filtering in high-impedance nodes rather than low-ESR power rails.
