Key Features
- 40-position dual-row surface mount terminal strip with 0.100" (2.54 mm) pitch for high-density PCB layouts
- Gold-plated contacts ensure low contact resistance and long-term reliability in demanding environments
- 4-wall housing construction provides superior mechanical support and prevents solder flux contamination during reflow
Applications
The TSM-120-04-H-DH-A-K-TR is well-suited for backplane interconnect systems, daughtercard attachment, and high-speed digital signal routing where a reliable 40-position surface mount interface is required. Its 0.100" pitch makes it compatible with standard PCB grid layouts used in industrial controllers, test equipment, and communication modules. The dual-row SMT footprint saves board space while maintaining robust mechanical and electrical connections.

Frequently Asked Questions
What is the pitch and row count of the TSM-120-04-H-DH-A-K-TR connector?
The TSM-120-04-H-DH-A-K-TR features a 0.100" (2.54 mm) pitch dual-row configuration providing 40 positions total across 2 rows of 20 contacts, compatible with standard 0.100" PCB grid spacing used in most digital board designs.
Which PCB assembly processes are compatible with the TSM-120-04-H-DH-A-K-TR surface mount terminal strip?
This connector is designed for surface mount technology (SMT) reflow soldering processes. Its 4-wall housing withstands standard reflow temperatures up to 260°C per JEDEC J-STD-020, making it compatible with lead-free solder paste processes and automated pick-and-place assembly.
When would a designer choose the TSM-120-04-H-DH-A-K-TR over a through-hole alternative for a backplane design?
A designer would select this SMT terminal strip when board thickness constraints limit through-hole via depth or when automated SMT-only assembly is required. The 40-position, 0.100" pitch layout supports up to 40 independent signal or power lines while keeping PCB footprint under typical dual-row through-hole alternatives, saving approximately 30% vertical clearance on 1.6 mm boards.
