44812 Datasheet, PDF (1/2 Pages) Molex Electronics Ltd. – 2.54mm (.100”) Pitch KK® Low Profile PC Board Receptacle

Low Profile KK^® Receptacle Combines Top and Bottom Header
Entry in One Connector
The new 44812 series Low Profile PC Board Connector is a significant step forward in updating the
KK product line to reflect customer’s needs in the 21st century. Utilizing terminal design features
from the SPOX™ family, Molex has been able to improve performance while shrinking the overall
package. The new design functions as both a top and bottom entry version, and retrofits into
existing KK .100” Pitch bottom entry PCB layouts. Overall connector height has been reduced by
almost 50%! The housing is made out of high temperature nylon for surface mount compatibility.
The new design also permits higher current ratings and a higher operating temperature.
Features and Benefits
■ 5.0A per line increases current carrying
capacity
■ Compact 4.5mm height above PC board
allows closer board stacking and is nearly
half the height of existing recptacles
■ Improved terminal design permits higher
operating temperatures, up to +105°C
■ Top and bottom entry mating provides
versatile design feature in one cost-conscious
style
■ Connector can be retrofitted into existing PC
board layouts which ensures convenient
transition with various mating headers
■ Surface-mount compatible housing
eliminates potential processing issues
