45911 Datasheet, PDF (1/3 Pages) Molex Electronics Ltd. – EXTreme PowerEdge™ Card Edge Hybrid Power Connector

FEATURES AND SPECIFICATIONS
The EXTreme PowerEdge™ Connector 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.
Features and Benefits
n Low-profile design allows high current transfer in
narrow spaces
n Mates to a 1.57mm (0.62”) PCB card edge
or bus bar
n Rated for current interruption hot-plugging
requirements
n Rugged power and signal contacts reduce the
potential for stubbing or damage
n 2 isolated power contacts or 8 signal contacts per
housing segment
n Available in 2, 3, and 4 segment versions
n Press-fit or solder tail PCB mounting
n End-to-end stackable to accommodate additional
circuit counts on card edge
