The 20 Ohm ESR is the spec that matters most for power rail decoupling — at switching frequencies above a few hundred kHz, the impedance is dominated by the ESR, not the capacitance. A 100 kHz ripple current of 50 mA pk-pk dissipates 50 mW in the ESR, which raises the internal temperature and accelerates aging. For a 6.3 V rail, the derating rule of thumb (50% margin) means the applied voltage should stay below 4.2 V to avoid surge failures. At the cold end, the capacitance shifts by about -10% from the 25°C value; at 125°C, the leakage current rises and the ESR increases by roughly 1.5×. The 0805 case size (2.05 mm x 1.30 mm) limits the heat dissipation — the part should not be placed next to a high-power inductor or regulator without thermal analysis. The part is in production and suitable for new designs.","metaTitle":"TAJR225K006SNJ KYOCERA AVX 2.2 µF Molded Tantalum Capacitor","metaDescription":"TAJR225K006SNJ from KYOCERA AVX: 2.2 µF ±10%, 6.3 V, 20 Ohm ESR, -55°C to 125°C.
