That ESR number is the key derating parameter: at the rated ripple current, the self-heating from the ESR adds to the ambient temperature, so the actual ripple current capability is limited by the 125°C maximum operating temperature. For a 10 V rail, the 1.3 Ohm ESR means the capacitor can handle about 270 mA RMS ripple before the internal temperature rise pushes past the derating curve — a useful sanity check when sizing the output filter of a buck converter or the decoupling on a high-current FPGA core rail. The molded case (Type Molded) provides mechanical stability across the thermal cycle, and the surface-mount 2312 (6032 Metric) footprint is a standard pad layout for reflow assembly.","metaTitle":"TAJC686K010H KYOCERA AVX 68 µF 10 V Molded Tantalum","metaDescription":"68 µF, 10 V, ±10% tolerance, 1.3 Ohm ESR, -55°C to 125°C, 2312 (6032 Metric) case.
