The components are laser trimmed to Marking achieve the required resistance tolerance. The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed circuits. Terminations Chips are packed and mounted with marking side up. The wrap-around terminations have an electroplated nickel The LRF3W Chips are mounted with the actual resistor barrier and matte tin finish, this ensures excellent leach element mounted face down on its termination pads. resistance properties and solderability.
