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.
