Product details

4.7 µF, 10 V — molded tantalum for decoupling and filtering

The TAJB475M010RNJ is a molded tantalum capacitor from KYOCERA AVX's TAJ series, rated at 4.7 µF with ±20% tolerance and a 10 V working voltage.

Active production — sourced per RFQ

Listed as Active.

This is the full military temperature band — the part holds capacitance and ESR across avionics cold-soak and engine-bay heat. For a 125°C ambient, derate the applied voltage to 67% of rated 10 V per standard tantalum practice.

Dimensions are 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. Surface-mount, compatible with standard reflow profiles. The molded construction provides mechanical stability and moisture resistance for general-purpose use.

Frequently asked questions

Can TAJB475M010RNJ be replaced with a ceramic capacitor?

A ceramic capacitor of the same capacitance and voltage rating will have much lower ESR (milliohms vs 4 Ohm) and no polarity, but ceramics exhibit DC bias derating — a 4.7 µF X5R in 1206 may drop to 2 µF at 10 V. Tantalum holds its capacitance across voltage and temperature. Evaluate the DC bias curve of the ceramic before substituting.

Is TAJB475M010RNJ RoHS compliant?

The evidence does not explicitly list RoHS compliance. KYOCERA AVX TAJ series molded tantalum capacitors are typically RoHS-compliant, but confirm with the datasheet or your compliance team for the specific date code.
