Product details

Molded tantalum for tight spots

The TAJT225K035RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, built for surface-mount assembly on boards where a 1411 (3528 Metric) footprint fits tight layout constraints. The 4.2 Ohm ESR sets the ripple current ceiling — a repair bench check: if the cap runs hot on a steady 100 mA ripple, the internal temperature rise may exceed the molded case rating.

The molded case and surface-mount package keep the part stable across thermal cycling; no conformal-coat compatibility issues on production boards.

Frequently asked questions

Is TAJT225K035RNJ equivalent to TAJT225K035M?

The evidence does not list a TAJT225K035M part or confirm equivalence. Compare the datasheet ratings — tolerance, voltage, ESR, and package dimensions — before substituting on a BOM line.

Can TAJT225K035RNJ be used for power supply filtering?

The 4.2 Ohm ESR limits ripple current handling — for high-ripple supplies, a lower-ESR tantalum or ceramic alternative may be needed.
