The 20 V rating gives comfortable headroom on a 12 V rail or a 5 V bus — you can run it at 80 % derating without pushing the voltage stress above the recommended limit for tantalum. For a decoupling cap on a 100 kHz switching regulator input, that ESR limits the ripple current to roughly 100 mA RMS before the internal temperature rise becomes significant. If your rail needs to handle more ripple, you'll want a larger case size or a polymer tantalum with lower ESR. The molded case handles the thermal cycling without cracking the dielectric — a common failure mode in conformally-coated tantalums subjected to rapid temperature swings. ## Active production — no EOL clock ticking No last-time-buy window, no NRND flag.","metaTitle":"TAJR105K020HNJ 1 µF 20 V Molded Tantalum Cap 0805 - KYOCERA","metaDescription":"TAJR105K020HNJ: 1 µF, 20 V, ±10%, molded tantalum capacitor in 0805 case.
