Key Features
- 66 positions dual-row SMT terminal strip on standard 0.100" (2.54 mm) pitch
- Straight-tail (STL) leads with uniform co-planarity for consistent reflow solder joint formation across all 66 contacts
- Gold contact finish (-K) provides low contact resistance and corrosion resistance for reliable long-term signal integrity
- Tape-and-reel (TR) packaging for automated pick-and-place SMT production at high volumes
- Dual-row (DH) format accommodates 66 signals in approximately 3.2 inches of PCB edge length
Applications
The TSM-133-04-STL-DH-A-K-TR is used in embedded computing backplanes, industrial controller motherboards, and multi-channel data acquisition cards where 66 surface-mount signal connections are required on a 0.100" pitch grid. The gold contact finish makes it particularly suitable for applications involving repeated mating cycles or environments where connector oxidation would degrade signal quality over time.

Frequently Asked Questions
How does the gold contact finish (-K) on TSM-133-04-STL-DH-A-K-TR improve long-term reliability compared with tin-finished variants?
The gold contact finish provides a noble metal surface that resists oxidation indefinitely at room temperature, maintaining contact resistance below 10 milliohms even after extended storage or repeated mating cycles. Tin-finished contacts can form oxide layers that increase resistance over time, especially in humid or industrial environments, making the gold finish the preferred choice for high-reliability applications requiring stable signal integrity across all 66 positions.
For a 66-signal dual-row interface, how does the body length of TSM-133-04-STL-DH-A-K-TR compare with single-row 66-pin headers at 0.100" pitch?
At 0.100" pitch, the dual-row TSM-133-04-STL-DH-A-K-TR places 66 contacts in 2 rows of 33, requiring a body length of approximately 3.2 inches. A single-row 66-pin header at the same 0.100" pitch would span approximately 6.5 inches, so the dual-row format saves about 3.3 inches of PCB edge space while keeping the same familiar 2.54 mm inter-contact spacing.
Is TSM-133-04-STL-DH-A-K-TR suitable for procurement in tape-and-reel quantities from global distributors, and what packaging quantities are typical?
Yes. The -TR suffix confirms tape-and-reel packaging, which is available from authorized SAMTEC distributors globally. Tape-and-reel connectors of this type are commonly supplied in reels of 200 to 500 pieces, supporting MRP-based replenishment planning and eliminating the manual handling overhead of tray or tube packaging when placing orders for production runs of 1,000 units or more.
