MTMM-118-10-G-D-350

Headers, Male Pins Overview

The MTMM-118-10-G-D-350 is a variable post height header strip manufactured by Samtec. It features a 2.00 mm pitch and a dual-row configuration with 10 positions per row, totaling 20 contacts. The connector utilizes phosphor bronze terminals with gold plating over a nickel barrier for reliable conductivity. Designed for through-hole mounting, it offers a straight installation angle and operates within a temperature range of -55°C to +125°C. The housing is constructed from black liquid crystal polymer (LCP) with a UL 94 V-0 flammability rating.

Headers, Male Pins Feature Summary

• Variable post height design allows customization of terminal length to accommodate specific board stacking requirements.
• Elastic stacking structure enables flexible positioning and accommodates varying assembly tolerances.
• Gold-plated phosphor bronze terminals provide durable electrical connections with low contact resistance.

Headers, Male Pins Applications

• Board-to-board interconnections in multi-layer PCB assemblies
• High-density electronic systems requiring customized pin heights
• Industrial control modules and communication equipment

Headers, Male Pins Procurement Notes

Verify the exact mating part number compatibility before integration, as the variable post height requires precise alignment with corresponding receptacles or sockets. Confirm that the specified terminal length meets the mechanical stack-up requirements of the target application. Ensure the through-hole soldering process parameters are compatible with the LCP material properties to prevent thermal damage during assembly.

Headers, Male Pins Selection Notes

Select this component when standard fixed-height headers do not meet the mechanical clearance or board thickness constraints of the design. The 2.00 mm pitch supports high-density layouts, while the dual-row format maximizes connection capacity within a limited footprint. Consider the current rating and operating temperature range to ensure suitability for the intended environmental conditions.

Headers, Male Pins Part Context

This part belongs to the MTMM series of modified through-hole headers, which are engineered for applications demanding flexible terminal lengths. The series provides designers with extensive options for pin counts and row configurations, supporting up to four rows and 200 terminals. The MTMM-118-10-G-D-350 specifically addresses needs for compact, reliable interconnects with customizable vertical dimensions.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include MTMM-118-10-G-D-070, MTMM-118-10-G-D-126, and MTMM-118-10-G-D-417, which share identical physical dimensions but differ in terminal height specifications. Verify that any replacement maintains the required 2.00 mm pitch and dual-row layout to ensure mechanical fit.

Headers, Male Pins FAQ

What is the maximum current rating for this connector?

The MTMM series supports a current rating of up to 3.2 Amperes per terminal.

Can the terminal height be adjusted after manufacturing?

No, the terminal height is fixed at the time of order. However, the elastic stacking design allows for slight positional flexibility during assembly.
