Active production — no last-time-buy window
The TAJB334K050HNJ: That means no forced last-time-buy; you can order it against your BOM quantity through independent distribution without a deadline.
No hand-loading or cut-tape handling needed — the reel feeds straight into the feeder.
This is a tantalum capacitor, not a generic MLCC. Tantalum offers stable capacitance over temperature and voltage, but it requires derating the applied voltage to 50-80% of rated to avoid surge failures. The TAJ series is the workhorse surface-mount tantalum line from AVX.
