Wrap-around terminations
(3 faces)
Construction
A thick film copper conductive element and organic
protection are screen printed on a 96% alumina substrate.
Terminations
The wrap-around copper terminations have an electroplated
nickel barrier and solderable coating, which ensures excellent
‘leach’ resistance properties and solderability. Chips can
withstand immersion in solder at 260˚C for 30 seconds and
are suitable for reflow or wave soldering processes.
Marking
The body protection is resistant to all normal cleaning solvents
suitable for printed circuits. Chips are marked R000 except for
0805 size which are not marked.
