Molded tantalum for tight thermal and mechanical margins
This TAJC475M020RNJ is a Molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 4.7 µF with ±20% tolerance and a 20 V working voltage. The molded case provides mechanical stability and moisture resistance, making it a standard choice for decoupling and filtering in power rails where board space is limited. The 2312 (6032 Metric) footprint (6.00 mm x 3.20 mm x 2.80 mm seated height) fits a compact layout, but the 0.110" max height demands clearance under low-profile components or enclosures.
At 125°C, tantalum capacitors require derating of the applied voltage — typically 50% of the 20 V rated voltage — to maintain reliability and avoid dielectric breakdown. Budget 10 V max at the hot end for a conservative design.
