Frequently Asked Questions
What pitch and how many positions does TMM-110-01-L-D-SM-A provide in its dual-row configuration?
TMM-110-01-L-D-SM-A provides 20 positions at 2.00 mm pitch in a dual-row low-profile layout. The 0.109-inch body depth keeps the connector height minimal, which is important in designs with tight vertical clearance between PCB layers or enclosures.
What contact finish does TMM-110-01-L-D-SM-A use and how does it affect mating durability?
The mating contacts use 10 µin gold plating over nickel, which provides low contact resistance and withstands many mating cycles. Gold plating is preferred for applications requiring reliable electrical connections in test fixtures or frequently reconnected assemblies.
Is TMM-110-01-L-D-SM-A compatible with standard lead-free reflow soldering processes?
Yes. The termination contacts use tin (Sn) over nickel (Ni) barrier finish, which is compatible with lead-free reflow soldering at standard peak temperatures around 260°C. The SMD pin format mounts directly to PCB pads for automated assembly.
What is the lead time for TMM-110-01-L-D-SM-A and does it include mechanical mounting support?
SAMTEC quotes approximately 2 weeks and 6 days factory lead time for TMM-110-01-L-D-SM-A. The connector includes a PEG board mounting option that provides additional mechanical alignment and stabilization on the PCB before and after soldering.
