With 300 mOhm ESR, this part handles moderate ripple currents typical of input/output filtering on 3.3 V or 1.8 V rails, but the 4 V rating means you must derate to 2 V or less for reliable operation — tantalum capacitors are sensitive to voltage surges above 50% of rated voltage.","metaTitle":"TAJY337K004RNJ – KYOCERA AVX 330µF 4V Molded Tantalum","metaDescription":"KYOCERA AVX TAJY337K004RNJ – 330µF ±10%, 4V, 300mOhm ESR, -55°C to 125°C.

The 4 V rating of this part is lower than 6.3 V, so the derated operating voltage (50% of 4 V = 2 V) is significantly less than what a 6.3 V part would allow (50% of 6.3 V ≈ 3.15 V). Check the rail voltage before substituting."},{"question":"What is the ESR of TAJY337K004RNJ?","answer":"The equivalent series resistance is 300 mOhm, measured at 100 kHz per the TAJ series datasheet.
