WK73R – Wide terminal high power thick film chip resistors
High reliability and enhanced terminal strength are essential in many power applications. KOA’s WK73R -series has a 90° rotated design and this offers several advantages compared to standard resistor footprints.
The 0612-chip size allows 6 x power rating compared to standard 1206 parts. This saves board space and is possible due to the improved heat dissipation via the solder joints.
The large terminals also enhance terminal strength and the smaller distance between the terminals reduces expansion stress increasing the solder joint reliability.
Finally, the inner resistive pattern is designed to minimize hotspots. These benefits combined, result in superior reliability compared to standard flat chip resistors in power applications.
