Save PCB Space with High Power Density Resistors from KOA

NEW: Increased Power Ratings

Special Flat Chip Resistors

  • Downsizing
    PCB space can be saved by using smaller parts from KOA's SG73 and WK73 series which allow the same power rating.
  • Power-up
    Alternatively, current layouts can be upgraded to allow higher rated power parts on existing footprints.
