Frequently Asked Questions
What is the pin count and row configuration of the TSM-149-04-LM-DV-P-TR?
The TSM-149-04-LM-DV-P-TR features 98 positions arranged in a dual-row layout with 2.54 mm (0.100 inch) pitch. This dual-row configuration provides 49 pins per row, enabling high-density connectivity while maintaining the standard 2.54 mm grid common in through-hole and SMT designs.
How does the surface mount design of TSM-149-04-LM-DV-P-TR benefit automated PCB assembly?
The SMT footprint allows the TSM-149-04-LM-DV-P-TR to be placed by automated pick-and-place machines and reflowed at standard solder temperatures, reducing assembly labor costs. The 4 mm mounting posts provide mechanical stability during the reflow process, ensuring the 98-position connector stays aligned to within 0.1 mm tolerance.
In which industrial or embedded applications is the TSM-149-04-LM-DV-P-TR a strong fit?
This connector is well-suited for backplane interconnects in industrial automation, mezzanine card interfaces in embedded computing, and data acquisition modules requiring 98 or more signal lines. Its dual-row 2.54 mm pitch format supports current ratings up to 3 A per contact, making it appropriate for mixed signal and power distribution boards.
When should an engineer choose TSM-149-04-LM-DV-P-TR over a single-row terminal strip of equivalent length?
A dual-row design like the TSM-149-04-LM-DV-P-TR delivers 98 contacts in roughly half the PCB length compared to a single-row strip with the same pitch of 2.54 mm. This matters when board length is constrained to under 127 mm but a large number of I/O signals, up to 98 lines, must be routed across a card-edge or mezzanine interface.
