board listing

[jcurrie]

found a old board in junk box it has two designations that i cant find listed anywhere it is a old early transistor IC mix , does the designated CF mean anything to any one there are three different packages one looks like a tantalum cap but has three leads the next looks like a cap, the last one is a can with 5 leads the numbers on all are a dead end, the other is ICP and lost the darn thing but it was a ceramic about 3/16 wide and high by 7/16 long with axelial leads no nomculature on it. thought CF might mean choke filter till i found the 5 pin can.

all a bit confusing
how about some pics so we can read part numbers etc

don't want to indenfy the componets just was wondering what CF and IPC on the board means like Q means transistor and IC or U means intergrated circuit.will try a photo after i get them off the board the info on them leads me nowhere in fact out of the 15 or so componets with readable info none of them are indefiable

who knows could mean anything
The manufacturer or their service manual would tell you

I have gear I service that has an IPC board in it, but I bet its totally different to yours

yea as the ICP isent a board just a componet that looks like a minture wire wound ceramic resistor, its a old sharps tv from the early 90's being the frugle person i;m i scrap old boards and keep indifable componets but this one a lot of them that i belive that sharps made then selves or had them made to there specks.

you still haven't given a pic
so that we can see what you are talking about

you don't have a mobile phone ??

no.nor a home phone

well found out what the CF means found another board with identical componet on it it was indentifyed as X101 so CF means crystal

 

[davenn]

or more specifically CF = Ceramic Filter

now if you have told us in your first post that it had X101 label on the board beside it
I could have told you that many posts ago

the orignal board listed it as CF501 wasn't till i found the same componet on another board calling it X101.
