What are the key features of TSM-133-03-TL-DH-A-K-TR?
- 66-position dual-row layout at 0.100" (2.54 mm) pitch for high-density SMT signal distribution
- Through-hole locating posts (DH option) providing accurate PCB alignment and improved mechanical stability during reflow
- Tape-and-reel (TR) packaging enabling automated high-volume surface-mount assembly
- TL (extended) tail length option offering enhanced solder-joint strength for vibration-prone environments
What is TSM-133-03-TL-DH-A-K-TR used for?
The TSM-133-03-TL-DH-A-K-TR is designed for high-pin-count surface-mount signal distribution on industrial backplanes, embedded computing modules, and test-instrument interface boards requiring 66 positions at 0.100" pitch. The dual-row dual-height (DH) body and through-hole locating pegs improve placement accuracy and resist misalignment during high-temperature reflow soldering. Tape-and-reel delivery supports automated SMT production lines with minimal manual handling.

Frequently Asked Questions
What does the DH designation mean on the TSM-133-03-TL-DH-A-K-TR, and how does it aid PCB assembly?
The DH designation stands for dual-height body with through-hole locating posts. These press-fit pegs, typically 1.0 mm in diameter, insert into PCB holes to lock the connector in position during pick-and-place and reflow at up to 260°C, preventing the 66-position part from shifting on the 0.100" (2.54 mm) pitch pads before solder solidifies.
How many signal positions does the TSM-133-03-TL-DH-A-K-TR provide, and what PCB area does its dual-row footprint occupy?
The TSM-133-03-TL-DH-A-K-TR provides 66 positions across 2 rows at 0.100" (2.54 mm) pitch, giving 33 positions per row. The total body length is approximately 83 mm (33 x 2.54 mm), making it suitable for backplane edge connectors and high-density I/O strips where 66 signals must be routed within a narrow board-edge zone.
Which SAMTEC mating connectors are compatible with the TSM-133-03-TL-DH-A-K-TR for stacking or wire-termination applications?
The TSM-133-03-TL-DH-A-K-TR is part of SAMTEC's TSM SMT terminal-strip family and mates with compatible TSW or TSM male headers at 0.100" (2.54 mm) pitch. Standard mating inserts in one motion, with typical contact normal force of 100 g per pin, ensuring reliable connectivity across all 66 positions in board-to-board and motherboard-to-module stack assemblies.
For industrial control designs subject to vibration, how does the TL tail on the TSM-133-03-TL-DH-A-K-TR improve solder-joint reliability?
The TL (tall or extended) tail option increases the solder-tail length beyond the standard, adding approximately 0.5 mm to 1.0 mm of additional solder-joint depth on 0.100" (2.54 mm) pitch pads. This extra solder fillet area raises fatigue resistance under thermal cycling from -40°C to +85°C and mechanical vibration, making the connector better suited for factory automation, motor control panels, and transportation electronics.
