For a 100 kHz switching ripple of 100 mA RMS, the internal dissipation is about 83 mW — that raises the core temperature above ambient and accelerates ageing. Keep the RMS ripple current below the thermal derating curve for the 125 °C ceiling. ## Temperature grade and board fit The 0805 footprint is a standard two-pad land pattern — no via-in-pad needed, but the solder mask between the anode and cathode pads must clear the 1.35 mm width to avoid tombstoning during reflow. No direct replacement within the same series — the size code P is fixed by the 0805 case and 2.2 µF / 20 V combination.","metaTitle":"TAJP225K020RNJ KYOCERA AVX Molded TAJ 2.2 µF 20 V ±10% 0805","metaDescription":"KYOCERA AVX TAJP225K020RNJ Molded TAJ series tantalum capacitor, 2.2 µF, 20 V, ±10%, 0805, -55 to 125 °C, ESR 8.3 Ohm.
