This makes it suitable for high-temperature environments like engine-bay electronics or downhole instrumentation where standard tantalums would derate or fail early. ## 0805 footprint — layout and sourcing posture Surface-mount 0805 (2012 Metric) package, dimensions 2.05 mm x 1.30 mm, seated height 1.20 mm max. The small footprint fits dense assemblies but demands careful pad geometry for reliable solder joint formation — follow the manufacturer's recommended land pattern.","metaTitle":"TAJR475M010SNJ Tantalum Capacitor – KYOCERA AVX 4.7 µF 10 V","metaDescription":"Active KYOCERA AVX TAJR475M010SNJ molded tantalum capacitor, 4.7 µF ±20% at 10 V, 0805 case, 9 Ohm ESR at 100 kHz.

Tantalum capacitors traditionally benefit from derating to 50-80% of rated voltage for reliability, especially at elevated temperatures. For a 10 V rail, a 16 V or 20 V rated part is common practice, but this part is specified for 10 V operation. Confirm the application's ripple and transient margin before committing."},{"question":"What is the ESR of TAJR475M010SNJ and why does it matter?","answer":"ESR is 9 Ohm at 100 kHz. This is the equivalent series resistance that dissipates heat under AC ripple. For a given ripple current, higher ESR means more self-heating, which accelerates aging and reduces lifetime — especially at 125°C. Budget this into the thermal design."},{"question":"What package size is TAJR475M010SNJ?","answer":"0805 (2012 Metric) case size, with dimensions 2.05 mm x 1.30 mm and a seated height of 1.20 mm max.
