TFM-145-31-S-D

Headers, Male Pins Overview

The TFM-145-31-S-D is a high-reliability Tiger Eye terminal strip header manufactured by Samtec. It features 90 positions arranged in a dual-row configuration with a 1.27 mm (0.05 in) pitch. Designed for through-hole mounting, this shrouded connector utilizes phosphor bronze contacts with gold plating to ensure signal integrity. The housing is constructed from black liquid crystal polymer (LCP), rated UL 94 V-0 for flammability. Electrical specifications include a current rating of 3.2 A and a voltage rating of 250 VAC, operating within a temperature range of -55°C to +125°C.

Headers, Male Pins Feature Summary

• High-reliability Tiger Eye interconnect system designed for robust board-to-board or cable connections.
• Shrouded four-wall design provides mechanical stability and protects against misalignment during mating.
• Push-pull locking mechanism ensures secure connection retention under vibration and shock conditions.
• Gold-plated phosphor bronze contacts offer low contact resistance and corrosion resistance.

Headers, Male Pins Applications

• ADSP-BF535 Blackfin EZ-KIT Lite development boards
• High-density digital signal processing hardware
• Industrial control systems requiring reliable interconnects
• Automotive electronics modules

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official Samtec documentation to confirm exact pin count, row configuration, and termination style. Ensure compatibility with mating female connectors regarding pitch and locking mechanisms. Check RoHS compliance status and moisture sensitivity levels prior to assembly. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Headers, Male Pins Selection Notes

Select this component when a 90-position, two-row header with 1.27 mm pitch is required for through-hole applications. Consider the TFM series if push-pull locking and high reliability are necessary. Evaluate thermal requirements against the -55°C to +125°C operating range. Compare current ratings of 3.2 A per contact against circuit demands. Ensure PCB layout accommodates the shrouded height and through-hole solder pad dimensions.
