Frequently Asked Questions
How many contact positions does the SQT-150-01-L-D provide, and how does the body length affect PCB space requirements?
The SQT-150-01-L-D provides 100 contact positions in a dual-row through-hole layout at 0.100" (2.54 mm) pitch, with a body length of 3.962 inches. This length accommodates 50 positions per row and requires a corresponding 3.962-inch footprint on the PCB, making it suitable for large backplane boards where high channel count and through-hole retention strength are required.
What is the contact finish specification of the SQT-150-01-L-D, and why does it matter for long-life test fixture applications?
The SQT-150-01-L-D uses gold (10 µin minimum) over nickel (50 µin minimum) mating contact finish. Gold provides excellent oxidation resistance and low contact resistance over many insertion cycles — typically rated for 500 or more mating cycles. In test fixture applications where connectors are mated and unmated frequently with devices under test, this finish maintains signal integrity far longer than tin-plated alternatives.
How does the FlexYZ compliant contact technology in the SQT-150-01-L-D benefit PCB assembly compared to standard press-fit or soldered through-hole connectors?
FlexYZ compliant contacts in the SQT-150-01-L-D create a gas-tight, solder-free mechanical connection when pressed into PTH PCB holes within the specified hole diameter tolerance. This eliminates the need for wave soldering the 100-position connector, reducing thermal stress on adjacent components and simplifying rework. The compliant zone absorbs PCB thickness tolerances while maintaining contact resistance below specified limits across all 100 pins.
