Samtec QTH Series Straight Surface PCB Header 80 Contacts 0.5 mm Pitch 2 Row Shrouded QTH-040-03-L-D-DP-A

The Samtec QTH-040-03-L-D-DP-A PCB Header is a precision-engineered electronic component designed for board-to-board interconnections in high-performance applications. Featuring 80 contacts arranged in 2 straight rows with a fine pitch of 0.5 mm, this connector facilitates compact and efficient circuit assembly.

The housing is made from durable black liquid crystal polymer, offering excellent mechanical strength and temperature resistance. Contacts are fabricated from phosphor bronze, a material known for its excellent conductivity and mechanical resilience, and plated with either gold or tin over a 50 μ" (1.27 μm) nickel base to ensure corrosion resistance and reliable electrical contact.

This header supports a voltage rating of 220VAC and a current rating of 2.2A, suitable for moderate power applications. It operates reliably across a wide temperature range from -55°C to +125°C, making it suitable for diverse industrial, electronics manufacturing, and laboratory environments.

The terminating solder type and surface mount design facilitate reliable PCB assembly and maintain signal integrity in electronic systems. The shrouded construction provides added protection to the contacts, preventing damage and misalignment during installation and operation.

High-speed ground plane terminal strip with 80 pins. 0.5 mm pole pitch ensures compact layout. Black liquid crystal polymer housing for superior insulation. Phosphor bronze contacts for enhanced conductivity. Gold or tin plating for corrosion resistance.
