Active production — no end-of-life signal
TAJY227K010RNJ carries an Active product status from KYOCERA AVX.
Rated at 220 µF and 10 V, this part suits 3.3 V and 5 V supply rails where a 50 % voltage derating margin is standard practice. The 10 V rating leaves headroom against transients, but it is not intended for 12 V rails — the applied voltage must stay below the rated limit with margin.
500 mOhm ESR and military temperature range
500 mOhm ESR is typical for a 220 µF tantalum in this package size. It handles general-purpose ripple currents without excessive self-heating, but high-ripple or high-frequency applications (e.g., SMPS output) may need a lower-ESR polymer or ceramic alternative.
2917 molded package — surface-mount assembly
The 2917 (7343 Metric) molded case measures 7.30 mm x 4.30 mm with a seated height of 2.00 mm. The Y case code is a standard footprint for tantalum capacitors, compatible with reflow soldering.
