Product details

The TAJA106K006HNJ: This is a KYOCERA AVX TAJ-series molded tantalum capacitor, 10 µF ±10% tolerance, rated at 6.3 V DC. The 1206 (3216 metric) case is a common footprint for bulk decoupling on 3.3 V or 1.8 V rails, where the 6.3 V rating gives headroom above the rail without over-speccing the voltage class.

4 Ohm ESR — what it means for ripple and self-heating

ESR is specified at 4 Ohm typical at 100 kHz. In a switching-regulator output filter, that ESR sets the ripple voltage and the internal self-heating. For a 10 µF cap at a few hundred mA ripple, the I²R loss is modest, but the 4 Ohm value means this part is better suited for bulk decoupling than for high-ripple output stages where a lower-ESR polymer would run cooler.

Frequently asked questions

Can TAJA106K006HNJ be replaced by TAJA106K006RNJ?

The RNJ suffix typically denotes a different termination finish (e.g., RoHS-compliant vs non-RoHS). Both share the same 10 µF, 6.3 V, 1206, ±10% ratings and TAJ series. Confirm the termination code matches your assembly process before substituting.

Is TAJA106K006HNJ RoHS compliant?

The HNJ suffix indicates a non-RoHS termination finish (tin/lead). If your assembly requires RoHS compliance, the RNJ or similar RoHS-compliant suffix variant is the correct choice. Check the specific termination plating for your reflow profile.

What is the operating temperature and lifetime rating?

Rated -55°C to 125°C with 2000 hours endurance at 125°C. That covers the full military temperature envelope and a typical hot-spot life of several years in continuous operation at 85°C ambient.
