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 2.54mm (.100”) Pitch KK® Low Profile PC Board Receptacle 44812 Top and Bottom Entry ■ ■ 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 SPECIFICATIONS Reference Information Packaging: Tray UL File No.: E29179 CSA File No.: LR 19980 Mates With: 4030, 4094, 42225, 42226, 42227, 42228, 42152, 42153, 42375, 42376, 42377, 42624 Designed In: Inches Electrical Voltage: 250 Volts AC (RMS) 176 Volts DC Current: 5 Amperes Contact Resistance: 30mΩ max. initial 10mΩ max. increase over initial Dielectric Withstanding Voltage: 1,000V Insulation Resistance: 1,000MΩ Mechanical Contact Insertion Force: N/A Contact Retention to Housing:15.6N min.
