If your BOM calls for a low-impedance bulk cap on a 1.8 V rail, this part's 20 Ohm ESR will dissipate more heat than a polymer or low-ESR tantalum alternative; the selection mistake is assuming all 4.7 µF caps are interchangeable. ## ESR and temperature derating For a 4.7 µF part, the ripple current rating is typically 0.1 A to 0.2 A RMS — confirm the application's ripple current against the manufacturer's derating curve before committing the BOM.","metaTitle":"TAJR475M002RNJ KYOCERA AVX TAJ Series 4.7 µF Molded","metaDescription":"TAJR475M002RNJ: 4.7 µF, 2.5 V, ±20%, 0805, -55°C to 125°C, 20 Ohm ESR.
