FTMH-138-02-F-DH-K-TR

Headers, Male Pins Overview

The FTMH-138-02-F-DH-K-TR is a surface mount micro terminal strip header manufactured by Samtec Inc. It features 76 positions arranged in two rows with a 1.00 mm (0.039 inch) pitch. The connector utilizes right-angle termination for board-to-board applications. Contact plating consists of gold flash over nickel, while the posts are tin-plated. The housing is black liquid crystal polymer (LCP) rated UL94 V-0. It supports a maximum current of 3.3 A per contact and withstands voltages up to 240 VAC or 330 VDC. Operating temperature ranges from -55°C to 125°C.

Headers, Male Pins Feature Summary

• Surface mount right-angle design for compact board-to-board interconnects
• Gold flash contact plating ensures reliable signal transmission
• High-density 1.00 mm pitch accommodates 76 positions in dual row configuration
• Thermoplastic LCP insulation provides thermal stability and flame resistance

Headers, Male Pins Applications

• Board-to-board connections in high-density electronic assemblies
• Signal routing in telecommunications infrastructure equipment
• Interconnects for industrial control systems requiring surface mount headers
• Data processing units utilizing micro terminal strips

Headers, Male Pins Procurement Notes

Verify the specific suffix 'K' indicates the keyed variant when sourcing replacements. Confirm that the 'TR' designation corresponds to tape-and-reel packaging for automated pick-and-place assembly processes. Ensure the gold flash plating specification matches the application's corrosion resistance requirements. Cross-reference the 76-position count with the dual-row layout to prevent mating errors during integration.

Headers, Male Pins Selection Notes

Select this component for applications requiring right-angle surface mount termination with a 1.00 mm pitch. The dual-row configuration maximizes pin density within limited board areas. Gold flash contacts are suitable for low-level signal applications where oxidation resistance is critical. Verify that the 3.3 A current rating and 240 VAC voltage limit align with the circuit's electrical demands before finalizing the design.

Headers, Male Pins Part Context

This part belongs to Samtec's FTMH series of micro terminal strips. The series offers various configurations including vertical and horizontal orientations with different post heights. The FTMH variant specifically denotes a right-angle surface mount header. These connectors are designed for high mating cycle durability and are often used in environments demanding precise alignment and robust mechanical retention.

Headers, Male Pins Replacement Considerations

FTMH-138-02-F-DH-TR serves as a non-keyed alternative with identical electrical and mechanical specifications except for the keying feature. Ensure the replacement maintains the 1.00 mm pitch and 76-position count. Verify that the right-angle orientation and surface mount termination remain compatible with the PCB footprint.
