The 4 Ohm ESR is a practical number for this case size: it limits ripple current to about 300 mA RMS at 85°C, which is enough for decoupling a 3.3 V rail or smoothing a low-power DC-DC output. The molded construction and general-purpose rating make it a straightforward drop-in for bulk decoupling or timing circuits.","metaTitle":"TAJR156M004RNJ – 15 µF 4 V Molded Tantalum Capacitor, 0805","metaDescription":"KYOCERA AVX TAJR156M004RNJ: 15 µF, 4 V, ±20% tolerance, 4 Ohm ESR, -55 to 125°C, 0805 case.
