Chip Resistors
High Power
Chip Resistors
SC3 Series
Construction
Resistive thick film material, overglaze and organic protection
are screen printed on a 96% alumina substrate. The
components are laser trimmed to achieve the required
resistance tolerance.
Terminations
copper have have an nickel
nickel and and ?nish. This ensures
The wrap-around terminations terminations electroplated electroplated
barrier barrier matte tin-lead solder coating, this ensures
excellent ‘leach ’ resistance properties and solderability.
Performance Data
Welwyn Components
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.
