The 20 V rating gives real derating headroom on a 12 V rail — tantalum caps need that margin to avoid field failures from voltage surges. Operating temperature spans -55 to +125 °C, so it fits avionics, downhole tools, or engine-bay electronics where the ambient climbs well past 85 °C. ## ESR and ripple — the bench limit you need to check ESR is 6 ohm at 100 kHz. That is on the higher side for a 2.2 µF tantalum — it limits the ripple current the cap can handle before self-heating becomes a problem. If this sits on a switching regulator output, check the ripple current budget against the ESR heating curve in the datasheet. Product status is Active. KYOCERA AVX is still producing this TAJ series code, so there is no imminent EOL or last-time-buy deadline. Sourced per RFQ through independent distribution.","metaTitle":"TAJR225K020RNJ KYOCERA AVX 2.2 µF 20 V Molded Tantalum","metaDescription":"TAJR225K020RNJ is an active KYOCERA AVX TAJ series molded tantalum capacitor, 2.2 µF ±10%, 20 V, 0805, ESR 6 ohm, -55 to 125 °C.
