The 1.5 Ohm ESR is the trade-off: it limits ripple current to about 1.6 A at 100 kHz, so this cap is a solid fit for bulk decoupling on a 4 V rail where the load steps are moderate, not for a high-frequency switching regulator output where you need sub-100 mOhm ESR. ## -55 to 125 °C — military temp, real-world deployment The molded package keeps the element dry; no conformal-coat worries on the capacitor body itself. You can design this into a new BOM today and expect it to be available for the production run.","metaTitle":"TAJB157K004RNJ KYOCERA AVX 150 µF Molded Tantalum Capacitor","metaDescription":"TAJB157K004RNJ from KYOCERA AVX: 150 µF, 4 V, ±10% tolerance, 1.5 Ohm ESR, -55 to 125 °C.
