The 3.1 Ohm ESR at 100 kHz sets the ripple current ceiling — for a 100 kHz switching regulator, the I²R loss in the capacitor is about 0.1 W at 180 mA ripple, well within the 0.125 W self-heating limit of a B case part. ## B case 1411 — footprint and layout fit Manufacturer size code B maps to the 1411 (3528 Metric) footprint: 3.50 mm x 2.80 mm body, 2.10 mm seated height. This is a common tantalum case size — the pad layout matches standard 3528 land patterns, so no footprint library update is needed if the BOM already uses a B-case tantalum. Surface-mount molded package, delivered on tape & reel (7-inch reel, 2000 pieces typical) or cut tape for prototype quantities. The molded construction gives better mechanical stability than conformal-coated parts under reflow and vibration.","metaTitle":"TAJB475K035RNJ – KYOCERA AVX Molded Tantalum Capacitor","metaDescription":"TAJB475K035RNJ is an active KYOCERA AVX molded tantalum capacitor, 4.7 µF, 35 V, ±10% tolerance, B case, 3.1 Ohm ESR, -55°C to +125°C.
