The ±10% tolerance keeps the timing or filtering corner within a narrow window across the reel. The 25 ohm ESR is typical for this size and voltage class — it limits ripple current handling, so this part is better suited for DC-blocking, timing, or low-ripple decoupling than for high-ripple bulk storage. A 12 V rail with a 5 V drop margin still leaves 15 V headroom at 125°C. ## Active production — no EOL pressure","metaTitle":"TAJS684K020RNJ KYOCERA AVX Molded Tantalum Capacitor 0.68","metaDescription":"TAJS684K020RNJ from KYOCERA AVX, TAJ series molded tantalum capacitor, 0.68 µF ±10%, 20 V, 1206 package, -55°C to 125°C.
