Samtec QTH-060-05-F-D-A Straight Surface Mount PCB Header, 120 Contacts, 2 Row, 0.5 mm Pitch, Shrouded, 2A, 175V

The Samtec QTH-060-05-F-D-A is a high-reliability, straight surface mount PCB header engineered for advanced electronic applications requiring compact size, high contact density, and consistent signal quality. This model is part of the QTH Series and provides 120 contacts in a 2-row configuration with an ultra-fine 0.5 mm pitch, supporting dense integration for modern PCBs.

The header body is manufactured from liquid crystal polymer for excellent mechanical stability, chemical resistance, and durability during soldering. Male contacts are constructed from phosphor bronze and gold-plated, offering low contact resistance and superior conductivity over extended service life. The shrouded body design reduces the risk of mismating and enhances mechanical protection during installation or servicing.

With a current rating of 2A and voltage rating of 175V, it is suitable for both signal and low-to-moderate power applications. The -55°C to 125°C operating temperature range allows use in harsh industrial, laboratory, and commercial conditions. Surface mount termination makes this header suitable for automated pick-and-place assembly, enabling cost-effective manufacturing of complex assemblies.

Typical applications include high-speed electronics, embedded systems, data communications equipment, industrial control boards, and any design requiring robust, high-density interconnects. The wire-to-board connector system fits modern electronics, instrumentation, and control system designs. Solder male contacts guarantee reliable PCB connections and facilitate secure mating with compatible sockets or cable assemblies.

This product is compliant with advanced speed requirements and is designed to support high-frequency and Gbps-class data transfer when matched with appropriate mating components. The QTH-060-05-F-D-A fulfills roles in test equipment, measuring instruments, signal interface boards, and compact module connections where high contact count and alignment integrity are essential.
