The 2 Ohm ESR means it handles moderate ripple current but will self-heat more than a low-ESR polymer cap; keep the ripple current below ~200 mA RMS at 85°C to stay inside the thermal derating curve. The molded case (type: Molded) and surface-mount 1411 (3528 Metric) package make it a direct fit for standard pick-and-place reflow assembly. ## Active — no end-of-life clock You can design this into a new BOM today without worrying about a last-time-buy window.","metaTitle":"TAJB156M020Y Tantalum Capacitor 15 µF 20 V","metaDescription":"TAJB156M020Y from KYOCERA AVX: 15 µF, 20 V, ±20% molded tantalum capacitor in 1411 (3528 Metric) package.
