The 2.5 Ohm ESR is the number that matters for ripple handling — a higher ESR means more self-heating under AC ripple, so this cap is better suited for bulk storage or bypass than for high-ripple output filtering. That means it holds its capacitance and leakage within spec across avionics cold-soak and engine-bay heat — not every tantalum does.","metaTitle":"TAJB685K020H KYOCERA AVX Molded Tantalum Capacitor 6.8 µF","metaDescription":"TAJB685K020H from KYOCERA AVX: 6.8 µF, 20 V, ±10% tolerance, 2.5 Ohm ESR, -55°C to 125°C, surface-mount 1411 case.
