Physical Data
_
*Recommended minimum pad & adjacent trace area for each termination for rated power dissipation on FR4 PCB
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 Pb-free 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.
