incorporates proven Molex design elements of high-performance
terminal contacts with redundant interface points for optimum mating of double-sided card edge gold fingers.
EXTreme PowerEdge™ offers 40.0A rating per contact, and 157.0 A per inch of PC board real estate. It is an
excellent low profile power card edge interface for applications where rugged single piece mating to a cardedge or
bus bar is needed and where space is at a premium. EXTreme PowerEdge™ is available in power only, signal only,
and power/signal combinations for design flexibility.

The need for high-current power interconnect solutions in increasingly smaller space continues to rise rapidly. Solving this power equation on new architectures and system
platforms has been a major focus for Molex product development teams. The new Molex EXTreme Power
®
family of products is the direct result of listening intently to
our customers’ electrical and mechanical design challenges. Since no two applications are the same, the Molex EXTreme Power
®
offering is comprised of several product
families that cover a wide range of current densities, mechanical envelopes, mating terminations and configuration choices that give system designers the ability to
