Surge & Pulse Stable Wide Terminal Chip Resistors WG73 Series

WG73 Series

High reliability and enhanced terminal strength are essential in all power applications. KOA’s wide terminal resistors offer several advantages compared to standard footprints.The 0612 chip size allows 4 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 new WG73 series has approx. 20 times the pulse handling capability compared to standard flat chip resistors of a similar size. The large terminals also enhance terminal strength and the smaller distance between the terminals reduces expansion stress.
