TMMH-148-01-G-T-RA

Headers, Male Pins Overview

The TMMH-148-01-G-T-RA is a low-profile board-to-board connector header manufactured by Samtec. It features 144 contacts arranged in three rows, providing a high-density interconnect solution. The connector utilizes a 2 mm (0.079 inch) pitch between contact positions. It is designed for right-angle surface mounting with through-hole solder termination. The housing is constructed from black Liquid Crystal Polymer (LCP), offering thermal stability and mechanical strength. Contact plating consists of gold over nickel to ensure reliable signal transmission.

Headers, Male Pins Feature Summary

• Low profile design suitable for space-constrained applications
• Right-angle orientation for efficient board stacking
• Gold-plated phosphor bronze contacts for durability
• Liquid Crystal Polymer insulator for heat resistance

Headers, Male Pins Applications

• High-density electronic assemblies
• Industrial control systems
• Telecommunications equipment

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official datasheets to confirm pin count, row configuration, and termination style. Ensure compatibility with mating receptacles regarding pitch and height. Check RoHS compliance status if required for your manufacturing process. Confirm that the right-angle orientation matches your PCB layout requirements before ordering.

Headers, Male Pins Selection Notes

Select this component when a high-contact-count, right-angle header is needed. The 2mm pitch allows for standard spacing while maintaining a compact footprint. Consider the LCP material properties for environments requiring higher thermal endurance compared to standard plastics. Ensure sufficient clearance above the board for the connector height.

Headers, Male Pins Part Context

This part belongs to the TMMH series of low-profile headers from Samtec. The series is characterized by its flexible shroud options and robust construction. The TMMH-148 variant specifically denotes a 148-position capacity, though this specific model may utilize a subset or full array depending on the exact configuration. It is widely used in modern electronics where reliability and density are critical.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 3-row, 144-pin configuration and 2mm pitch. Compatible alternatives include other Samtec TMMH models with identical electrical ratings and mechanical dimensions. Verify that any replacement maintains the same right-angle orientation and gold plating specification to ensure interface compatibility.
