44-Position SMT Receptacle for Board-to-Board Stacking
Each contact is rated 2 A at 200 V, with gold-plated mating surfaces (1.97 µinch) over phosphor bronze.
Board Footprint and Routing Considerations
The SMT pads must align with the mating header's tail pattern — the receptacle's insulation height is 4.50 mm, which sets the mated stack height when paired with a Minitek 2.00mm header.
The base product number is 55510; the -044LF suffix denotes the 44-position, gold-plated, SMT variant in tube packaging.
