The molded case provides mechanical stability and moisture resistance for surface-mount assembly. The 4.5 Ohm ESR (equivalent series resistance) is a key parameter for power-supply decoupling and filtering: higher ESR limits ripple current handling and increases self-heating, so budget the ripple current against the ESR derating curve in the datasheet. ## Surface-mount footprint and polarity Packaged in the 1411 (3528 Metric) case, size code B, with dimensions 3.50 mm x 2.80 mm and a seated height of 2.10 mm max. The molded body is polarized — the anode (+) is marked on the top surface; reverse-voltage connection can damage the part. The ±10% tolerance is tight enough for most decoupling and timing circuits; for precision filters, confirm the capacitance drift over temperature and voltage bias.","metaTitle":"TAJB225K025SNJ KYOCERA AVX Molded Tantalum Capacitor 2.2µF","metaDescription":"TAJB225K025SNJ KYOCERA AVX TAJ series molded tantalum capacitor, 2.2 µF, 25 V, ±10%, 4.5 Ohm ESR, -55°C to 125°C.
