The ESR also sets the output ripple voltage: 500 mOhm × ripple current gives the AC drop across the cap. For a switching regulator running at 500 kHz, the 500 mOhm ESR dominates the impedance at the switching frequency — the ceramic bypass cap on the output handles the higher-frequency content. Rated from -55 to 125 °C, this cap lives in the same temperature band as military and aerospace silicon — avionics black boxes, downhole logging tools, satellite power supplies, and engine-bay ECUs all run in this range. The 125 °C ceiling means the cap can sit next to a hot MOSFET or regulator without derating the voltage — tantalum caps do not lose voltage rating with temperature the way ceramics do. ## 2312 case — common footprint for 47 µF/20 V The 2312 metric case (6.00 mm × 3.20 mm, 2.80 mm seated height) is a standard tantalum footprint shared across multiple manufacturers — the land pattern matches the EIA 6032-28 pad geometry. Manufacturer size code C confirms the case dimensions; the 0.110-inch seated height fits under most low-profile heatsinks or enclosure lids.","metaTitle":"TAJC476K020RNJ — 47 µF 20 V Molded Tantalum, TAJ Series","metaDescription":"47 µF ±10% 20 V molded tantalum capacitor in 2312 case.
