TFM-140-02-S-S-A

Headers, Male Pins Overview

The TFM-140-02-S-S-A is a surface mount header from the Samtec Tiger Eye TFM series, featuring an 80-position configuration in a single row. It utilizes a 1.27 mm (0.050 inch) pitch with square pin contacts made of phosphor bronze. The connector employs a liquid crystal polymer insulator rated UL94 V-0 and offers a current rating of 3.7 A per contact at 250 VAC. Operating temperatures range from -55°C to +125°C, and it includes alignment pins for precise mating.

Headers, Male Pins Feature Summary

• Shrouded design with polarized and keyed features for reliable board-to-board or wire-to-board interconnects
• Square pin contacts ensure positive mating and secure retention within the housing
• Surface mount termination facilitates automated pick-and-place assembly processes

Headers, Male Pins Applications

• High-density electronic assemblies requiring precise alignment
• Industrial control systems utilizing discrete wire connections
• Automotive electronics modules demanding robust thermal stability

Headers, Male Pins Procurement Notes

Verify that the specific suffix 'S' confirms single-row configuration rather than dual-row variants. Confirm RoHS compliance status matches project requirements. Ensure PCB footprint dimensions align with the manufacturer's recommended layout guidelines to prevent soldering defects during surface mount processing.

Headers, Male Pins Selection Notes

Select this component when a single-row 1.27 mm pitch header is required for high-density applications. Consider the shrouded design for improved mating accuracy compared to open-frame alternatives. Evaluate the 3.7 A current rating against system power distribution needs to ensure adequate performance margins under operating conditions.

Headers, Male Pins Part Context
