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.","metaTitle":"TAJR334K025RNJ KYOCERA AVX TAJ Series 0.33 µF Molded","metaDescription":"Active 0.33 µF ±10% 25 V molded tantalum capacitor in 0805 case. -55°C to 125°C range, 17 ohm ESR.
