HTST-120-01-SM-DV-P-TR

Headers, Male Pins Overview

The HTST-120-01-SM-DV-P-TR is a .100" (2.54 mm) pitch high-temperature shrouded terminal strip manufactured by Samtec Inc. This surface-mount header features a dual-row configuration with 120 positions, designed for robust board-to-cable or board-to-board interconnections. The component utilizes phosphor bronze contacts with gold plating over nickel and tin termination finishes to ensure reliable signal transmission. It is housed in a polyester (PCT) insulator rated UL 94 V-0 for flame resistance. The unit supports mixed technology terminations and operates within a temperature range of -55°C to +125°C, meeting RoHS and REACH compliance standards.

Headers, Male Pins Feature Summary

• High-temperature shrouded design ensures secure cable mating and alignment
• Mixed technology surface mount termination facilitates flexible PCB assembly
• Gold-plated phosphor bronze contacts provide durable electrical conductivity
• UL 94 V-0 rated polyester insulation offers thermal stability and flame resistance

Headers, Male Pins Applications

• Industrial control systems requiring high-temperature reliability
• Automotive electronics and sensor interfaces
• Telecommunications equipment and network infrastructure
• Medical device internal interconnects

Headers, Male Pins Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm that the 120-position count matches the required circuit density. Ensure the surface-mount footprint aligns with the manufacturer's recommended land pattern. Check for RoHS compliance requirements if operating in regulated regions. Validate the high-temperature rating against the operational environment specifications.

Headers, Male Pins Selection Notes

Select this model when a shrouded header is necessary to prevent misalignment during cable insertion. The mixed-technology termination allows compatibility with both through-hole and surface-mount processes. Consider the 2.54 mm pitch for standard spacing requirements. Evaluate the high-temperature capability if the application involves soldering profiles exceeding standard limits. Compare against non-shrouded alternatives if space constraints are critical.

Headers, Male Pins Part Context

This component belongs to Samtec's HTST series, which specializes in high-temperature shrouded terminal strips. The series is engineered for demanding environments where standard connectors may fail due to heat or mechanical stress. The HTST line provides a rugged solution for securing cables to printed circuit boards, offering superior retention compared to open-frame headers.
