G & P types E & F types
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 and100% tin plating and are
suitable for soldering.
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.
