If the application draws higher ripple current, the ESR causes a temperature rise that accelerates aging; the 125°C rating provides headroom. ## Package fit and footprint decision The case size is 1411 (3528 Metric) and also listed as 1210 — the 3.50 mm x 2.80 mm footprint with a seated height of 1.20 mm. This dual footprint listing means the land pattern matches both standard 1411 and 1210 pads, so the same PCB layout accepts this part or a ceramic X5R/X7R in a 1210 package without a board spin. The size code T on the body identifies the case dimensions at a glance during inspection. The molded construction and general-purpose feature set mean no special screening, but the temperature rating itself is the selection gate for harsh-environment BOMs.","metaTitle":"TAJT475M016RNJ KYOCERA AVX TAJ Series 4.7 µF 16 V Molded","metaDescription":"TAJT475M016RNJ from KYOCERA AVX: TAJ series molded tantalum, 4.7 µF ±20%, 16 V, 3.1 Ohm ESR, -55°C to 125°C, 1411/1210 SMD.
