HTMS-109-54-G-D

Headers, Male Pins Overview

The HTMS-109-54-G-D is a through-hole micro header manufactured by Samtec Inc. It features an 18-position configuration arranged in a dual row (2 rows). The contact pitch is 0.050 inches (1.27 mm), with a row spacing of 0.100 inches (2.54 mm). The connector utilizes male pin contacts made of phosphor bronze, plated with 10 µinches of gold over nickel in the mating area. It is designed for straight mounting and solder termination. The housing is constructed from black liquid crystal polymer (LCP) with a UL 94 V-0 flammability rating. The operating temperature range spans from -55°C to +125°C, and it carries a current rating of 5 A per contact.

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against the official Samtec datasheet to confirm plating thickness and lead style variations. Ensure the ordering part number matches the required contact count and row configuration. Cross-reference the environmental compliance status, such as RoHS and REACH, with current manufacturer declarations before procurement. Confirm that the through-hole termination method aligns with the assembly process capabilities.

Headers, Male Pins Selection Notes

Select this component when a dual-row through-hole header with a 1.27 mm pitch is required. The 10 µin gold plating provides durability for repeated mating cycles. Consider the 5 A current rating and 125°C temperature limit for thermal management. Verify mechanical clearance for the straight orientation and ensure the PCB footprint matches the specified dimensions.

Headers, Male Pins Part Context
