Construction: Thick film resistor material, overglaze and organic protection are screen printed on a 96% alumina substrate. Wrap-around terminations have an electroplated Ni barrier and pure Sn matte finish, ensuring 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.
