What are the key features of TSM-145-01-SS-DV-P-TR?
- 90-position dual-row 2.54mm pitch SMT terminal strip with 3A per contact current rating for power and signal applications
- Gold-plated SS (single-sided) contacts with DV vertical orientation enabling reliable connection to matching TSM header series
- Tape-and-reel (TR) packaging and P (polarized) keying feature preventing incorrect mating during automated board assembly
What is TSM-145-01-SS-DV-P-TR used for?
The TSM-145-01-SS-DV-P-TR is designed for high-density PCB-to-PCB and wire-to-board interconnects in industrial control, test and measurement, and embedded computing systems. Its 90-position dual-row 2.54mm pitch layout provides 90 signal or power connections in a compact SMT package, ideal for backplane daughter card and modular system designs. The polarized keying prevents mis-mating, improving assembly reliability in high-volume production environments.

Frequently Asked Questions
What is the pin count, pitch, and current rating of the TSM-145-01-SS-DV-P-TR?
The TSM-145-01-SS-DV-P-TR provides 90 positions in a dual-row layout with 0.100 inch (2.54mm) contact pitch. Each contact carries up to 3A, and the connector is rated for operating temperatures from -55°C to +125°C. This combination makes it suitable for both signal and moderate-power distribution on densely populated SMT boards.
How does the polarization (P) feature of the TSM-145-01-SS-DV-P-TR prevent assembly errors?
The P suffix on the TSM-145-01-SS-DV-P-TR indicates a polarization key that physically prevents the 90-position connector from being inserted in the wrong orientation. This mechanical feature is especially valuable in automated assembly lines where high-volume placement of dual-row 2.54mm connectors can result in orientation errors, reducing rework costs and field failure rates for mission-critical equipment.
For a backplane design needing 90 connections at 2.54mm pitch, how does the TSM-145-01-SS-DV-P-TR compare to lower-pin-count alternatives?
Compared to using multiple smaller connectors such as three 30-position TSM series parts, the 90-position TSM-145-01-SS-DV-P-TR eliminates two extra mating interfaces and reduces board area consumed by connector footprints by approximately 15%. The single 90-position strip also simplifies PCB routing by consolidating all signals into one continuous row pair, which is advantageous in backplane designs where signal integrity management of 90 connections is required.
