What are the key features of TFM-138-32-L-D-A-P-TR?
- 76-position dual-row 0.050-inch (1.27 mm) pitch terminal strip enabling high-density signal routing in compact SMT PCB designs
- Low-profile right-angle (L) termination style minimizes connector height above the PCB for space-constrained mezzanine and stacking applications
- Polarization peg (P) prevents reversed-orientation mating and tape-and-reel (TR) format supports automated high-volume SMT assembly
What is TFM-138-32-L-D-A-P-TR used for?
The TFM-138-32-L-D-A-P-TR is engineered for high-density mezzanine board stacking, FPGA expansion modules, and compact telecommunications line card interfaces where a low-profile right-angle 0.050-inch pitch connector is required. Its 76-position dual-row layout routes a large number of signals in a footprint roughly half the length of an equivalent 0.100-inch pitch connector. The polarization peg and tape-and-reel packaging together reduce assembly errors and support efficient automated SMT production for high-volume designs.

Frequently Asked Questions
What does the low-profile right-angle termination style mean for PCB height requirements of the TFM-138-32-L-D-A-P-TR?
The low-profile right-angle (L) termination on the TFM-138-32-L-D-A-P-TR orients the mating interface parallel to the PCB surface and reduces the connector's profile above the board to approximately 2 mm or less, compared to standard vertical configurations. This is critical in stacked mezzanine assemblies and compact enclosures where board-to-board clearance is limited to under 5 mm.
How many contacts does the TFM-138-32-L-D-A-P-TR provide and how does its 0.050-inch pitch compare to 0.100-inch alternatives?
The TFM-138-32-L-D-A-P-TR provides 76 contacts in a dual-row arrangement at 0.050-inch (1.27 mm) pitch. Compared to a 0.100-inch (2.54 mm) pitch connector, this doubles the signal density per unit PCB length, allowing 76 signals to occupy the same footprint that a 0.100-inch pitch connector would need for only 38 contacts.
Which design scenarios benefit most from the polarization peg on the TFM-138-32-L-D-A-P-TR?
The polarization peg on the TFM-138-32-L-D-A-P-TR is most beneficial in automated assembly environments and field-service applications where a 76-position, 0.050-inch pitch connector could be inserted in reverse orientation. Mis-mating a reversed connector can damage all 76 contacts and the connected PCB circuitry instantaneously, making the mechanical keying peg a critical safeguard for protecting expensive FPGA and computing board assemblies.
