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 solderable 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 Resistance
The body protection is resistant to all normal industrial cleaning solvents suitable for printed circuits.
