Capacitance and voltage for rail filtering
This TAJW155K050RNJ is a 1.5 µF, 50 V rated tantalum capacitor in the molded TAJ series from KYOCERA AVX.
Temperature range and ESR for harsh environments
The 3.1 Ohm ESR at 100 kHz means the self-heating from ripple current is manageable for a 1.5 µF part — budget the I²R loss into the thermal design if the ripple exceeds 200 mA RMS.
