Samtec QTH Series Straight Surface PCB Header, 40 Contacts, 0.5 mm Pitch, 2 Row, Shrouded, 220V, QTH-020-01-F-D-DP-A-K

The Samtec QTH-020-01-F-D-DP-A-K PCB Header is a straight surface mount, high-speed ground plane terminal strip engineered for reliable board-to-board interconnects in densely populated electronic assemblies. This header features 40 contacts, positioned in a dual-row, shrouded configuration with a fine 0.5 mm pitch, making it ideal for tight spacing and compact circuit layouts.

Its robust housing is made from black liquid crystal polymer, combining excellent dielectric properties with mechanical strength for surface mount applications. The contacts are manufactured from phosphor bronze and are finished with gold plating over nickel, optimizing the connector for reliable electrical performance, corrosion resistance, and long-term durability in repeated mating cycles.

Key features include support for 220V operation, a maximum current rating of 2.2A, and a wide operating temperature range from -55°C up to 125°C, enabling this header to function effectively in environments subject to thermal variations. The straight, shrouded design aids in correct connector alignment and secure mating against accidental decoupling, while the surface mount solder terminations ensure ease of assembly onto PCBs.

This Samtec PCB header supports board-to-board systems used in industrial control equipment, instrumentation, automation electronics, embedded and computing hardware, and wherever high-density interconnections are critical. The header’s shrouded housing protects the contacts during handling and insertion, while the precise 0.5 mm pitch enables designers to maximize signal density and reduce PCB footprint.

Engineered for demanding applications, this component is suitable for professional production, laboratory development, and rapid prototyping where consistent electrical contact and thermal stability are vital. The product's combination of material quality, advanced plating, and precision alignment makes it a robust choice for manufacturers and system integrators seeking reliable surface mount connectors for modern high-speed electronic assemblies.
