The components are laser trimmed to achieve the required resistance tolerance. Terminations The wrap-around copper terminations have an electroplated nickel barrier and tin-lead solder coating, this ensures excellent ‘leach’ resistance properties and solderability. Chips can withstand immersion in solder at 250˚C for 90 seconds and are suitable for reflow or wave soldering mounting applications. Marking The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed circuits. Chips are packed and mounted with marking side up. The SC3 Chips are mounted with the actual resistor element mounted face down on its termination pads. 1000 100 100mm2 300mm2 1000mm2 Termination Pad Area (each end) Temperature Rise (˚C) 1 watt 2 watt 3 watt Pulse Power Rating 100 0.010.11.0 Time (sec) Power (watts) The wrap-around terminations have an electroplated nickel barrier and matte tin finish.
