  • Is reliability and enhanced terminal strength essential in your power application

    KOA's WK73-series has a 90° rotated design and offers several advantages compared to standard resistor footprints. A three times higher power rating in case of 0612 vs 1206 size is the most visible. This can save board space and is based on the improved heat dissipation through the solder joints. Much higher terminal strength is related to the bigger soldering area. The lower distance between the terminals, results in less expansion stress to the solder joints. The inner resistive pattern causes less temperature rise. All the above mentioned benefits combined, result in a superior reliability compared to standard flat chip resistors.
