Product details

0.33 µF 25 V molded tantalum — TAJ series fit

The TAJR334K025RNJ: This is a 0.33 µF ±10% 25 V molded tantalum capacitor from the TAJ series, in an 0805 (2012 metric) case. The 17 ohm ESR is the number that matters for ripple filtering — at 0.33 µF the capacitor's self-resonant frequency is high enough that ESR dominates impedance in the 100 kHz to 1 MHz range where most switching regulators operate.

Active production — no EOL signal

The 0805 case keeps the board footprint small, but the 17 ohm ESR means it cannot carry much ripple current — derate the AC component per the datasheet curve.

Frequently asked questions

What is the equivalent capacitor for TAJR334K025RNJ?

Any 0.33 µF ±10% 25 V molded tantalum capacitor in an 0805 case with the same R-size code from the TAJ series is a functional equivalent. The ESR of 17 ohm is the key differentiator — a lower-ESR substitute may change the ripple attenuation in the circuit.
