Active71,669 in stock

Overview

The S7271-45R is a C-shape surface mount spring contact designed to provide reliable electrical grounding and RFI shielding between a PCB and an external component or chassis. Constructed from copper alloy with a gold flash plating, it offers a 2.00mm free height and is optimized for a 1.50mm working height. This low-profile contact is supplied on tape and reel packaging for high-speed automated assembly.

Why Choose This Part

The component features a pre-loaded C-shape design that ensures consistent contact force and high durability over its operating temperature range of -40 to +85 degrees Celsius. Its gold-plated finish prevents oxidation and ensures reliable electrical conductivity even in environments where corrosion might otherwise occur. The surface-mount footprint includes a dedicated pick-and-place zone, making it ideal for high-volume automated production lines.

Applications

EMI/RFI Shielding
Providing a low-impedance path between a PCB ground plane and a metal shield can or enclosure to minimize electromagnetic interference.
Chassis Grounding
Establishing a secure electrical connection between the internal electronics and the metal housing of a device for safety and signal integrity.
Antenna Feeds
Acting as a pressurized contact for connecting internal PCB traces to external antenna structures in mobile or hand-held devices.
