For a 0.68 µF cap at 20 V, the AC ripple current that produces a 10°C temperature rise is roughly 50 mA RMS — stay below that to keep the part within its rated temperature range. In a decoupling role on a 20 V rail, this cap handles the high-frequency transients where the ESR dominates the impedance. ## Temperature grade — field-replacement fit The molded case (type: Molded) resists moisture and mechanical stress better than a conformally-coated chip — important when you are swapping it on site without a conformal-coat bake.","metaTitle":"TAJT684M020RNJ KYOCERA AVX Molded Tantalum Capacitor 0.68µF","metaDescription":"KYOCERA AVX TAJT684M020RNJ molded tantalum capacitor, 0.68µF ±20%, 20V, 15 Ohm ESR, -55°C to 125°C.
