In order to eliminate possible moisture entrapment and the resulting potential outgassing effects during the soldering process, most surface mount tantalum capacitor manufacturers offer a dry pack option.
If the part is shipped in dry pack, the parts must be assembled via process handling requirements per J-STD-033 for MSL 3.
As one example, TAJA226K010RNJV from AVX can be ordered with the suffix ‘V’ after the part number to specify the Dry Pack Option.
Here is the comparison between with “V” and without “V”.
