Active production — no allocation pressure
The TAJS225M020RNJ: Listed as Active — this is a current-production part with no last-time-buy or allocation signals.
Molded tantalum, military temperature range
The TAJS225M020RNJ is a molded tantalum capacitor in the TAJ series, rated 2.2 µF ±20% at 20 V. The 4.5 Ohm ESR means self-heating under AC ripple is the derating driver; a 20 V rail with 100 mV ripple at 100 kHz dissipates roughly 2.2 mW, well within the 125°C limit.
1206 footprint, SMD reflow profile
Surface-mount 1206 (3216 Metric) case, size code S. The 3.20 mm x 1.60 mm footprint with 1.20 mm seated height fits standard reflow profiles — no special bake or moisture sensitivity label beyond typical tantalum handling.
