The 1.8 Ohm ESR is the series resistance that governs ripple current heating and output ripple voltage — for a 100 kHz switching regulator output, that ESR adds about 40 mV of ripple per 22 mA of AC ripple current, which is high enough to matter in a low-noise rail. The molded case handles the thermal cycling without the mechanical stress that can crack conformally-coated wet tantalums. ## Package footprint and board-fit note The 1206 case measures 3.20 mm x 1.60 mm with a seated height of 1.00 mm max. That low profile fits under a 1.2 mm clearance, but the 1.0 mm height means the pick-and-place nozzle must be set for a thin component — standard 1206 chip capacitors are typically 1.6 mm tall, so the feeder tape pocket depth and nozzle vacuum pressure should be verified during setup to avoid tombstoning.","metaTitle":"TAJK226K004RNJ – KYOCERA AVX 22 µF 4 V Molded Tantalum","metaDescription":"Active KYOCERA AVX TAJ series 22 µF ±10% 4 V molded tantalum chip in 1206 case. 1.8 Ohm ESR, full military temp range.
