What are the key features of TSM-135-01-F-DH-A-K-TR?
- 70 positions in dual-row 0.100 inch pitch for maximum signal density in SMT connector applications
- Gold-plated (K) contacts providing superior corrosion resistance and reliable low-contact-resistance mating
- F (flush) mounting style for low-profile PCB installation minimizing connector standoff height
- Tape and reel (TR) packaging enabling automated SMT pick-and-place at high production volumes
- DH dual-row configuration doubling pin count versus single-row at equivalent board footprint length
What is TSM-135-01-F-DH-A-K-TR used for?
The TSM-135-01-F-DH-A-K-TR is designed for high-density backplane interconnects, PCB stacking headers, and signal routing interfaces in communications equipment, industrial controllers, and test and measurement instruments requiring 70 pins at 0.100 inch pitch. Its gold-plated contacts make it particularly suitable for applications demanding reliable repeated mating cycles, such as plug-in module connectors and field-replaceable board assemblies.

Frequently Asked Questions
How do the gold-plated contacts of TSM-135-01-F-DH-A-K-TR improve reliability compared to tin-plated alternatives in high-cycle connector applications?
Gold-plated contacts (K suffix) in TSM-135-01-F-DH-A-K-TR maintain contact resistance below 20 milliohms over thousands of mating cycles, whereas tin-plated contacts may oxidize and increase contact resistance after 50 to 100 cycles in humid or industrial environments. Gold is preferred for connectors mated more than 100 times, such as removable modules and test fixture sockets where signal integrity at low voltages and currents must be preserved.
For a 70-pin interface in a backplane design, what PCB footprint length does TSM-135-01-F-DH-A-K-TR require compared to a single-row 70-pin connector?
TSM-135-01-F-DH-A-K-TR uses a dual-row DH layout with 35 contacts per row at 0.100 inch (2.54 mm) pitch, requiring approximately 3.5 inches of connector body length. A single-row 70-pin connector at the same pitch would need approximately 7 inches, so the dual-row design saves roughly 3.5 inches of PCB edge space — a significant advantage in compact backplane or panel designs.
Which applications require the flush mounting (F suffix) style of TSM-135-01-F-DH-A-K-TR rather than standard raised or elevated mounting?
The F flush mount configuration in TSM-135-01-F-DH-A-K-TR seats the connector body closer to the PCB surface, minimizing standoff height to less than 2 mm above the board. This is important in low-profile enclosures, sandwich-style board stacks, or designs where a mating connector must engage at a minimal board separation of 5 mm to 8 mm, and where a taller connector body would prevent proper seating.
Is TSM-135-01-F-DH-A-K-TR available in tape and reel format suitable for automated assembly, and what minimum order quantities apply?
Yes, the TR suffix confirms that TSM-135-01-F-DH-A-K-TR is supplied on tape and reel for automated pick-and-place assembly. Samtec typically packages TSM series reels with 500 to 1000 pieces per reel depending on connector length, and orders below reel minimums may require a cut-tape or tray surcharge. Verifying reel quantity and MOQ with the distributor before BOM finalization avoids unexpected cost adders in low-to-medium production runs.
