The TAJA475K020RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 4.7 µF with ±10% tolerance and a 20 V DC voltage rating. The 1206 (3216 Metric) case, size code A, measures 3.20 mm × 1.60 mm with a seated height of 1.80 mm. This footprint is common across many tantalum and ceramic capacitor families, making it a drop-in candidate for existing board layouts.
The evidence does not list a specific RoHS compliance statement, but KYOCERA AVX tantalum capacitors in the TAJ series are generally RoHS-compliant. Confirm with the manufacturer's latest documentation if your BOM requires a formal compliance certificate.
The equivalent series resistance is 4 Ohm at 100 kHz, which is typical for a size A case at this capacitance and voltage rating. This ESR value should be factored into ripple current calculations and decoupling network design.
