Hello all,

we have received some 2N 3441 JANTX power silicon transisitors in a TO-66
body, which are showing evidence of rust around the "top hat" section.
Unfortunately this component is one of the growing number that have become
obsolete.

My questions;

 is this rust likely to have an adverse effect over the passage of time?

Is there a way of removing/neutralising it to prevent furher deterioration?

The part is for an Aero application and will be conformally coated in
service.

as ever, your advice would be greatly appreciated.
