CONSTRUCTION
A metal film layer is deposited on a
high grade
ceramic body (aluminium
oxide). This resistive layer
is trimmed
to its nominal value and on both ends a
contact is made which will
guarantee optimum
solderability. This
is achieved by applying several
layers
and for ease of soldering the outer layer
consists of Ni/matte tin.
The resistive layer is
covered with a
protective coating.
