Greetings all,

Came into a fair amount of Harris TV transmitter boards that have 4 of these chips on them. Looking for the MSDS on them for safe handling of the white ceramic.

Stopped cleaning the boards until I get some material info.

Look very healthy from a Au perspective.

Any advice is appreciated.

Thanks !

Thanks Butcher for accelerating the possible remarking possibilities.

I'd likely just sell the complete boards with 4 ea.

Interesting that the date codes are 95 vintage and from China on the eBay ones. Mine are 03.

Not sure how you'd "refurbish" one other than reflow and try to remove solder.

Still very interested in the yield.

Regards
 
"Refurbish", probably translates from foreign languages into reusing the old parts not repairing them...

I searched for the data sheets for these parts, apparently the data is somewhat hard to find online, I have a barn full of old data books, when I get a chance I will look through some of the Phillips data books and see if I can find some more information on these.
