Key Features
- 100 contacts on ultra-fine 0.5 mm pitch in a dual-row SMT header, enabling high-density board-to-board connections in space-constrained designs
- 10 µin gold over 50 µin nickel mating contact finish for reliable low-resistance connections through many mating cycles
- Low-profile body (0.066 inch depth) with positioning pin for accurate PCB placement, minimizing alignment errors in automated assembly
Applications
The LTH-050-01-G-D-A is designed for high-density board-to-board interconnections in portable consumer electronics, medical devices, and compact communication modules where space is critical. Its 0.5 mm pitch and 100-contact dual-row layout allow routing of up to 100 signals across a 1.15-inch body in an extremely thin SMT profile. The integrated positioning pin ensures consistent alignment between mated boards, supporting reliable operation in vibration-prone environments.

Frequently Asked Questions
How does the LTH-050-01-G-D-A's 0.5 mm pitch help achieve high-density interconnects on compact PCBs?
At 0.5 mm pitch, the LTH-050-01-G-D-A fits 100 contacts in a dual-row SMT header with a body length of only 1.15 inches. This is half the footprint of a 1.0 mm pitch equivalent, enabling engineers to route 100 signals in portable devices such as wearables and handheld instruments where PCB area is extremely limited.
What role does the positioning pin play during assembly of the LTH-050-01-G-D-A, and how does it affect soldering quality?
The integrated positioning pin registers the LTH-050-01-G-D-A to its PCB footprint before reflow, preventing lateral shift of the 100-contact, 0.5 mm pitch body during solder paste melting. This mechanical registration reduces solder bridging risk and improves first-pass yield on automated SMT lines handling fine-pitch components.
When would a designer choose the LTH-050-01-G-D-A over a higher-pitch SAMTEC board-to-board header?
Engineers select the LTH-050-01-G-D-A when they need 100 signals in the smallest possible footprint, as its 0.5 mm pitch reduces connector length to 1.15 inches compared to roughly 2.3 inches for a 1.0 mm pitch alternative carrying the same count. It is the preferred choice for compact medical diagnostic modules, camera boards, and RF front-end daughter cards where board area is the primary constraint.
