Intensifying our approach to provide high-current

density and a customer-configurable design, EXTreme

Power-Mass offers a nearly unlimited range of power

and signal module-design options, providing customer-

specific interconnect solutions for AC and DC power

requirements. EXTreme Power-Mass is a high-current,

board-to-board, modular connector system, providing

350.0A per inch.

EXTreme Power-Mass is designed to support power

supplies and systems requiring very high-current

transfer in challenging thermal-constrained spaces.

EXTreme Power-Mass complements Molex’s robust

EXTreme power-connector family offering. For more

High-current, custom configurable, board-to-board connector system delivers up to 350.0A per

inch

n

Multiple power (150.0A, 80.0A, 40.0A) and signal

(24 to 64 circuits) modules available to provide

maximum flexibility for customer design

requirements

n

350.0A per inch current density is one of the

highest capacity board-to-board power connectors

on the market

n

Less than 1 milliohm resistance (plane-to-plane) at

end-of-life provides minimum heat generation with

maximum current transfer

n

Press-fit and solder-board termination for easy and

reliable PCB mounting options

n

Die-cast or plastic guides provide rugged blind-

mating capabilities

n

Modules assembled to metal stiffener to assure true

position and flexible module placement

n

Sequential power-blade and signal-pin lengths

facilitates post-mate and pre-mate options
