Chemi-con released a notice in 2003 (attached in this post) maintaining that none of their series in production at the time used the quaternary salts, including SXE, whose older datecodes were also known leakers. But I noticed LXJ was not included in that document. I initially thought it was because it was going out of production at the time. Maybe the real reason is due to the usage of quaternary salts in the electrolyte.  |
Seen that notice from NCC. LXJ is not as prone to leak from the bung as the noted ones.. but when they leak, they wreck PCB traces just like the others. The only brand from that era that I don't see pee on the board from the bung are Pannies, even HFQ.
Even then, rubber does decompose after decades. It doesn't help when ammonia/ammonium attacks rubber and some plastics, expediting the process.
