The 20 V rating gives 60% derating margin on a 12 V supply — enough headroom for typical automotive load-dump transients without needing a higher-voltage part. ESR is specified at 2 Ohm — this sets the ripple current limit and output voltage ripple in a switching regulator. At 100 kHz switching frequency, the ripple voltage from the capacitor alone is 2 Ohm times the inductor ripple current; the rest comes from the output capacitor's bulk value. The part can sit in an avionics LRU that sees -40°C cold-soak at altitude and 105°C near the engine firewall, or in a downhole tool that cycles from surface ambient to 125°C wellbore — the tantalum anode construction holds capacitance across the band better than MLCC. ## Package — size code C, 2312 Manufacturer size code C, 2312 (6032 Metric) — 6.00 mm x 3.20 mm footprint, 2.80 mm seated height. The 2.80 mm height fits standard 2.5 mm board-to-board spacing with clearance. Surface-mount reflow profile per JEDEC J-STD-020 for tantalum; no special bake required below MSL 3. No direct pin-compatible alternative from AVX, but the TAJ family covers the same footprint and ratings.","metaTitle":"TAJC685K020RNJ KYOCERA AVX TAJ Series 6.8 µF 20 V ±10%","metaDescription":"TAJC685K020RNJ – Active KYOCERA AVX molded tantalum capacitor, 6.8 µF, 20 V, ±10%, 2 Ohm ESR, -55°C to 125°C.
