Physical Data
Construction
Thick film resistor material, overglaze and organic protection
are screen printed on a 96% alumina substrate. Wrap-around
terminations have an electroplated nickel barrier and solder
coating, this ensures excellent ‘leach’ resistance properties
and solderability.
Marking
Components are not marked. Reels are marked with type,
value, tolerance, date code and quantity.
Solvent Resitance
The body protection is resistant to all normal industrial
cleaning solvents suitable for printed circuits.
