Product details

Active production — 22 µF molded tantalum for harsh environments

The TAJD226K020PNJ is an active KYOCERA AVX TAJ series molded tantalum capacitor rated at 22 µF with a 20 V working voltage and ±10% tolerance. The molded case provides consistent mechanical protection and supports reflow soldering in surface-mount assembly.

ESR and ripple current — what 900 mOhm means for your rail

For a 22 µF output capacitor on a 500 kHz buck converter, the ripple current at 50 mA pk-pk produces roughly 2.25 mW of internal dissipation — well within the package's thermal budget at 85°C ambient. At higher ripple levels, derating the applied DC voltage by 50% per tantalum best practice keeps the failure rate below 1 FIT.

Sourcing — active with multi-source reach

The 2917 (7343 Metric) package is a standard tantalum footprint shared across multiple manufacturers, simplifying second-source qualification.

Frequently asked questions

Can TAJD226K025PNJ be used as a replacement for TAJD226K020PNJ?

TAJD226K025PNJ is a higher-voltage variant (25 V vs 20 V) in the same TAJ series and 2917 package. It is a drop-in replacement for the 20 V part as long as the higher voltage rating does not conflict with derating guidelines for tantalum capacitors in your circuit. Confirm capacitance, tolerance, and ESR match your design requirements.
