I just bought some BJT's OnSemi's low Vcesat high gain NJT4031NT1G and
complementary NJT4030PT1G.

They came with an advisement "Caution this bag contains Moisture
Sensitive Devices" Level #3
Where level 3 is
"floor life out of bag"
168 hours <30 C/60% RH
Does this mean that these BJT's would only last 168 hours shelf life
when taken out of the bag? This doesn't make any sense what if you use
these in a circuit that only see's intermittent use will the BJT specs
deteriorate?
I have no immediate need for these I just got them to test them out
switching speed,vcesat and gain.
I usually store my smd components rewraped in antistatic bags and
labeled in coin envolopes. I dont revacum seal them though. Would this
method still work for components with Moisture warnings?
