Power Ratings of Wide Terminal Type Flat Chip Resistors Significantly Increased
2025.03.18
Terminal temperature specifications enable even higher power
WK73R/WK73S
KOA's WK73R/WK73S which are wide terminal type flat chip resistors have a structure with large electrodes for excellent heat dissipation and can apply higher power compared to short-side electrode resistors of the same size.
It is now possible to guarantee even higher power ratings by applying terminal temperature regulations and reviewing the specifications to WK73R/WK73S.
As a result, the series has accomplished higher rated power in all sizes from 0204 inch to 1225 inch, including a guaranteed maximum rated power of 4 W in the 1225 inch size(WK73S).
The category power enables high power application even at high temperatures and power can be applied up to
0.833 W at 155°C in the 0508 inch size(WK73S).Compared to general-purpose chip resistors (RK73 series),
it contributes to downsizing of circuits and reduction in the number of components. AEC-Q200 Tested.
(Applications)
Car electronics, power supply, industrial equipment, etc.
