The 1206 (3216 Metric) case and surface-mount package make it a drop-in for general-purpose decoupling, filtering, and timing circuits where a stable, low-leakage electrolytic alternative is needed. The 7.9 Ohm ESR is the key thermal parameter: at ripple currents typical of a 20 V rail, this ESR limits self-heating to a few degrees Celsius, but the capacitor should not be used as a bulk output filter in a high-ripple switching regulator without checking the ripple current derating. The molded case provides mechanical robustness and moisture resistance over this range. It can be specified for new designs without obsolescence concern.","metaTitle":"TAJA684M020RNJ KYOCERA AVX Molded Tantalum Capacitor 0.68","metaDescription":"TAJA684M020RNJ from KYOCERA AVX: Molded tantalum, 0.68 µF ±20%, 20 V, 7.9 Ohm ESR, -55°C to 125°C, 1206 case.
