Flat Chip Size vs. Power Rating

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.

RS73 Series High Precision Resistors ESD Tolerant

KOA’s new RS73-series are ESD transient tolerant high precision and high reliability resistors using thick film technology.

With a T.C.R. down to ±25ppm and a tolerance as low as ±0.1%, the new RS73-series from KOA is ideal for precision designs such as high-accuracy sensing or voltage detection circuits in automotive, industrial and measuring applications, where ESD sensitivity is an issue.


UR73V Series Thick Film Current Sensing Resistor

KOA’s UR73V-series automotive approved low ohm resistors are designed for current sense applications in demanding environments. The special facedown construction of the VD-version makes lower resistance values with a low T.C.R. possible.

The facedown construction means that the total T.C.R. is minimized due to the shorter current path in the electrodes and solder fillet. The low T.C.R of new...
