SG73P Series – Space Saving Anti Pulse Chip Resistors

SG73P: Power Pulse Tolerant Chip Resistors

The SG73P series has approx. 7 times pulse handling capability compared to standard flat chip resistors. Due to the special resistance trimming it also allows a higher continuous power rating. This means that existing designs can be "powered up": An SG73P device can be dropped onto the pads of a similar sized conventional part, thus increasing the power…

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.

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…
