The 12 Ohm ESR is the headline parameter for a tantalum: it governs the ripple current the part can handle before self-heating shifts the capacitance. ## Derating and ESR budget Tantalum capacitors require voltage derating: a 10 V rated part should see no more than 50-60% of rated voltage in continuous service, so 5-6 V DC bias is the practical ceiling. The ±20% tolerance is standard for tantalum electrolytics — the capacitance at -55°C can drift toward the low end of the band, so a 2.2 µF part may measure 1.76 µF at cold. If the downstream circuit (e.g., an RC time constant or a hold-up cap) needs a tighter window, a ±10% tantalum or a ceramic alternative should be considered.","metaTitle":"TAJS225M010SNJ KYOCERA AVX TAJ Series 2.2 µF 10 V Molded","metaDescription":"TAJS225M010SNJ from KYOCERA AVX: TAJ series, 2.2 µF, 10 V, ±20%, 1206 case, 12 Ohm ESR, -55°C to 125°C.

The core electrical ratings — 2.2 µF, 10 V, ±20%, 12 Ohm ESR, 1206 case — are identical between the two order codes.
