What are the key features of TSM-135-04-H-DH-A-K-TR?
- 70 positions dual-row at 2.54 mm (.100") pitch for high-density board-to-board SMT connections
- Extended height (H) body profile provides component clearance for stacked PCB designs
- Dual-row layout maximizes signal count within a compact horizontal footprint
- Tape-and-reel (TR) packaging for automated SMT assembly line compatibility
- Gold-plated contact terminations for reliable low-resistance electrical connections
What is TSM-135-04-H-DH-A-K-TR used for?
TSM-135-04-H-DH-A-K-TR is used in embedded computing systems, data acquisition boards, and modular industrial electronics where the taller body height provides needed clearance over components on the lower PCB. The 70-position dual-row SMT format is well-matched to memory interfaces, mezzanine card designs, and multi-function I/O expansion modules.

Frequently Asked Questions
How does the high-profile (H) body of TSM-135-04-H-DH-A-K-TR differ from standard-height 70-pin SMT strip connectors?
The H variant of TSM-135-04-H-DH-A-K-TR features an elevated body height compared to the standard profile TSM series, providing greater clearance between stacked PCBs. This is critical when the mating board has tall SMD components or heat sinks exceeding 4 mm in height, which standard-height 70-pin SMT connectors cannot accommodate without interference.
For a mezzanine card design requiring 70 signal channels, what stack height does TSM-135-04-H-DH-A-K-TR support when mated?
The TSM-135-04-H-DH-A-K-TR mates with compatible SAMTEC SSQ or SFM socket strip series on a 2.54 mm (.100") dual-row grid, providing 70 signal channels at mated stack heights typically ranging from 11 mm to 15 mm depending on the chosen mating header height. This suits mezzanine card assemblies with modest inter-board spacing requirements.
Is TSM-135-04-H-DH-A-K-TR suitable for RoHS-compliant designs, and what is the recommended reflow profile?
Yes, TSM-135-04-H-DH-A-K-TR carries lead-free (RoHS) compliant construction. SAMTEC recommends a peak reflow temperature not exceeding 260°C per IPC/JEDEC J-STD-020 guidelines, with a time-above-liquidus of approximately 30 seconds. These parameters ensure reliable solder joint formation for the 70-pin SMT footprint without thermal damage to the housing.
