Construction
Planar gold G type or PtAg P types: Electrodes, resistor material
and overglaze are printed onto an alumina substrate. The
resistors are laser trimmed to the required value and protected.
Wraparound EW type: Thick-film PtAg electrodes, resistor
material and overglaze are printed onto an alumina substrate.
The resistors are laser trimmed to the required value and
protected. The terminations are wraparound coated with a
polymer Ag material.
Wraparound GW type: These are made as the EW type then
plated with a nickel barrier and Gold. All termination styles are
suitable for attachment with conductive adhesive.
Marking
The components are not marked; all data is printed onto the
packaging.
Solvent Resistance
The component is resistant to all normal industrial cleaning
solvents suitable for printed circuits.
