I've been asked if a design of mine can be immersed in transformer oil. (And still function properly!) The circuitry is mostly SMT Qs, ICs, Rs, ceramic Cs all of which I think are OK but I'm unsure about a couple types of components - Aluminum Electrolytic Caps and Connectors.
Oil type: I don't have that info and it could vary between installations but I assume paraffin or silicone based oil.
The components I am most unsure of are:
Aluminum Electrolytic capacitors such as United Chemi-Con EMZF500ADA101MJA0G.
Connectors, specifically Molex 22-23-2041 and On Shore Technologies OSTOQ045450.
The boards are conformal coated with polyurethane.
Any advice on component evaluation or cautionary advice would be greatly appreciated. Thank you!
