The 1.5 Ohm ESR is a design parameter: it limits the ripple current the capacitor can handle without self-heating, and it sets the zero in the control-loop compensation of the downstream regulator. Housed in the 1411 (3528 Metric) case, size code T, the capacitor measures 3.50 mm x 2.80 mm with a seated height of 1.20 mm — a low-profile footprint that fits under a heatsink or on the back side of a dense PCB. Surface-mount, supplied on tape and reel — compatible with standard pick-and-place and reflow profiles for the TAJ series.","metaTitle":"TAJT686K004RNJ KYOCERA AVX TAJ Series 68 µF Molded Tantalum","metaDescription":"TAJT686K004RNJ: 68 µF, 4 V, ±10% tolerance, 1.5 Ohm ESR, -55°C to 125°C.
