TMM-122-05-G-D

Headers, Male Pins Overview

Samtec Inc. TMM-122-05-G-D is a Low Profile Tiger Eye Header Strip featuring a 2 mm (0.079 in) pin-to-pin spacing. This component provides 44 positions arranged in two rows, designed for through-hole mounting with a straight orientation. The contacts are constructed from phosphor bronze and feature gold plating on both the mating and termination sections. It utilizes liquid crystal polymer (LCP) insulation rated UL 94 V-0, supporting an operating temperature range of -55°C to +125°C with a current rating of 3.2 A per contact.

Headers, Male Pins Feature Summary

• Low profile design optimized for space-constrained board-to-board or cable applications
• Gold-plated phosphor bronze contacts ensure reliable signal integrity and corrosion resistance
• Unshrouded header configuration allows for flexible mating options

Headers, Male Pins Applications

• Board-to-Board interconnects
• Cable-to-Board connections
• General purpose electronic assemblies requiring low-profile headers

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required 44-position, 2-row configuration with gold plating. Confirm that the through-hole mounting style aligns with the target PCB layout. Ensure environmental requirements meet the specified -55°C to +125°C operating range and UL 94 V-0 flammability rating before finalizing procurement.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-density connection is required for 2 mm pitch applications. The gold plating offers superior conductivity compared to tin variants, making it suitable for sensitive signal lines. Consider the unshrouded design if guide pins or other retention methods are utilized in the assembly process.

Headers, Male Pins Part Context

The TMM series represents Samtec's Low Profile Tiger Eye Header Strips, engineered for compact electronic designs. These headers provide robust mechanical stability while minimizing vertical space usage. The TMM-122-05-G-D specifically addresses needs for higher density connections within the standard 2 mm pitch family.

Headers, Male Pins Replacement Considerations

TMM-122-05-G-D-SM serves as a surface mount alternative within the same series. For tin-plated equivalents, consider TMM-122-05-T-D. Verify pin count and row configuration when substituting.
