What are the key features of TSM-139-04-LM-DV-P-TR?
- 78-position dual-row configuration on 0.100" (2.54 mm) pitch for standard-density PCB interconnects
- Tape-and-reel packaging (TR suffix) optimized for automated SMT pick-and-place at high production volumes
- Gold-plated contacts rated at 3 A per pin, ensuring low contact resistance and long insertion life across -55°C to +125°C
What is TSM-139-04-LM-DV-P-TR used for?
The TSM-139-04-LM-DV-P-TR is a high-position-count SMT terminal strip suited for backplane interconnects, industrial control boards, and test-and-measurement equipment that require reliable signal distribution across 78 lines in a compact dual-row layout. Its tape-and-reel packaging makes it ideal for high-volume automated assembly lines where throughput and placement accuracy are critical.

Frequently Asked Questions
How many positions and what pitch does the TSM-139-04-LM-DV-P-TR have?
The TSM-139-04-LM-DV-P-TR provides 78 positions arranged in a dual-row layout on a 0.100" (2.54 mm) pitch, allowing it to mate with standard 0.100" headers and carry up to 3 A per contact, making it suitable for both signal and light power distribution on a single connector.
Why choose the tape-and-reel (TR) variant for production assembly of the TSM-139-04-LM-DV-P-TR?
The TR suffix indicates tape-and-reel packaging compatible with standard SMT pick-and-place machines, enabling high-speed placement rates of hundreds of parts per hour, reducing manual handling errors, and supporting IPC-7711 rework standards for 78-position SMT terminal strips in volume production.
What operating temperature range does the TSM-139-04-LM-DV-P-TR support, and in which industrial applications is it commonly used?
Rated from -55°C to +125°C, the TSM-139-04-LM-DV-P-TR is well suited for industrial automation controllers, motor drive interfaces, and ruggedized test equipment that must operate reliably through wide ambient temperature swings without connector derating.
