Samtec Straight Surface Mount PCB Header, LSEM-120-03.0-L-DV-A-N-K-TR, 40 Contacts, 0.8mm Pitch, 2 Row, Shrouded

Samtec LSEM-120-03.0-L-DV-A-N-K-TR straight surface mount PCB header features 40 male contacts spaced at a 0.8mm pitch across 2 rows, making it ideal for high-speed, high-density electronic interconnects. This header employs a shrouded board-to-board configuration, ensuring robust mechanical protection and secure mating.

The gold-plated phosphor bronze contacts deliver superior electrical performance, combined with a liquid crystal polymer housing for excellent thermal and electrical properties. Designed for surface mounting and solder termination, this component supports demanding applications across industrial, laboratory, and commercial electronics.

With a current rating of 1.8A and voltage tolerance up to 225/318V AC, the header operates reliably in temperature ranges from -55°C to 125°C. Its hermaphroditic self-mating design streamlines inventory, and the razor beam contacts provide high mating and unmating force, giving an audible 'click' when securely connected.

Suitable for surface mount installations in PCB design. Two rows of 40 shrouded contacts for high-density and high-speed signal transmission. Hermaphroditic layout ensures flexible stacking and interconnection. A slim, ruggedized body enables space-saving and durability.

Gold plating enhances conductivity and prevents corrosion. Ideal for use in parallel, perpendicular, and coplanar board systems. Compatible with industrial, laboratory, manufacturing, and commercial applications.

This product finds use in applications demanding high-speed, reliable connections such as embedded systems, instrumentation, electronic prototyping, and development boards. Its versatile design enables stacking heights from 6mm to 12mm when combined with compatible connectors, allowing design flexibility.
