Frequently Asked Questions
What pitch and row configuration does the TFM-144-05-LM-D-LC use?
The TFM-144-05-LM-D-LC uses a .050" (1.27 mm) pitch in a dual-row configuration, providing 144 positions total. This compact spacing allows high-density interconnects on boards where space is constrained, making it ideal for mezzanine and backplane applications.
How does the LC laser-cut option on TFM-144-05-LM-D-LC improve connector reliability?
The LC laser-cut contact option delivers tighter dimensional tolerances on the contact tines, resulting in more consistent mating forces across all 144 positions. This precision reduces signal path resistance variation and supports reliable performance over 200 or more mating cycles in automated test and communications hardware.
In which system architectures is the TFM-144-05-LM-D-LC most commonly deployed?
This connector is commonly deployed in networking switches, data storage arrays, and test instrumentation where a 144-pin, .050" pitch SMT connector bridges mezzanine cards to a motherboard. The low-profile LM contact style keeps stacking height under 5 mm, preserving chassis clearance in 1U and 2U rack systems.
