What are the key features of TFM-145-04-S-D-LC?
- 0.050 inch (1.27 mm) pitch dual-row configuration delivers 90 contacts in a compact high-density PCB footprint
- Low-clearance (-LC) profile minimizes board-to-board stacking height for ultra-thin module designs
- Tiger Eye contact geometry maintains high normal force and sub-20 milliohm contact resistance across repeated mating cycles
What is TFM-145-04-S-D-LC used for?
The TFM-145-04-S-D-LC is ideal for high-density board stacking in embedded computing modules, FPGA mezzanine cards, and RF daughterboards where a low-clearance 0.050 inch pitch connector must accommodate 90 signal circuits in a minimal height envelope. Its robust Tiger Eye contact design supports applications in industrial automation, aerospace avionics, and test instrumentation requiring reliable multi-cycle mating. Engineers select this part when ultra-thin module stacking and high circuit count must be achieved simultaneously.

Frequently Asked Questions
What stacking height advantage does the -LC (low-clearance) option provide in the TFM-145-04-S-D-LC?
The -LC suffix designates a low-clearance mated height, which reduces the board-to-board gap compared to standard-profile TFM connectors. For a 90-position, 0.050 inch pitch dual-row connector, this reduced clearance can save several millimeters of vertical space in stacked module designs, enabling thinner end products such as rugged embedded computing platforms and compact avionics line-replaceable units.
How many signal circuits can the TFM-145-04-S-D-LC route, and what contact pitch supports that density?
The TFM-145-04-S-D-LC provides 90 positions in a dual-row layout at 0.050 inch (1.27 mm) pitch. This density allows 90 independent signal circuits within a connector body roughly 57 mm long, which is substantially more compact than achieving the same circuit count with a 0.100 inch pitch header that would require more than 114 mm of board length.
When would a procurement engineer choose TFM-145-04-S-D-LC over a lower-position-count TFM variant?
A procurement engineer selects the 90-position TFM-145-04-S-D-LC when a design requires more than 72 circuits at 0.050 inch pitch without adding a second connector. Consolidating 90 signals into a single connector reduces the BOM line count, simplifies PCB routing, and cuts assembly labor compared to using two smaller TFM connectors, which is particularly valuable in cost-sensitive, high-volume embedded module production.
