For a 100 µF cap on a 100 kHz switching rail with 100 mA ripple current, the internal dissipation is roughly 14 mW — the temperature rise stays negligible inside the -55 to 125 °C operating range. If the ripple current doubles, the power loss quadruples and the cap runs hotter; at that point a larger case or lower-ESR polymer becomes the better fit.","metaTitle":"TAJA107K004RNJ 100 µF 4 V Tantalum Capacitor – KYOCERA AVX","metaDescription":"KYOCERA AVX TAJA107K004RNJ: 100 µF ±10%, 4 V, 1.4 Ohm ESR, 1206 case, -55 to 125 °C.
