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. The gold terminations are suitable for wire bonding and both types are suitable for
attachment with conductive adhesive. Wraparound E 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 and are suitable for attachment with conductive adhesive. Wraparound F type: These are made as the E type then
plated with a nickel barrier and 100% tin plating and are suitable for soldering.
Marking
The components are not marked; all data is printed onto the packaging.
Solvent Resistance
General Note
The component is resistant to all normal industrial cleaning solvents suitable for printed circuits.
TT Electronics reserves the right to make changes in product specification without notice or liability.
