Product details

4.7 µF tantalum for 125°C ambient — ESR and lifetime

KYOCERA AVX TAJR475M010SNJ is a molded tantalum capacitor from the TAJ series, rated 4.7 µF at 10 V with ±20% tolerance. 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.

Frequently asked questions

Does TAJR475M010SNJ require voltage derating for a 10 V rail?

The rated voltage is 10 V. 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.

What is the ESR of TAJR475M010SNJ and why does it matter?

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.

What package size is TAJR475M010SNJ?

0805 (2012 Metric) case size, with dimensions 2.05 mm x 1.30 mm and a seated height of 1.20 mm max. The manufacturer size code is R.
