SQW-105-01-L-Q Application Field and Working Principle

SQW-105-01-L-Q is part of the SQW series of rectangular connectors – headers, receptacles, and female sockets from Samtec. This connector is one of the most popular rectangular connectors on the market today and is often used for RF, pin, and midplane applications.

SQW connectors are a type of flexible, high-speed, and low-profile connection for circuit board interconnects, typically deployed in a wide range of telecommunication and computing products. It has a two-piece design and incorporates a 0.050 inch pitch contact system for even further reduced contact resistance and improved signal integrity.

The SQW-105-01-L-Q connector is available in two unique styles; the L-Style (horizontal) and the Q-Style (diagonal). The Q-Style is used to interconnect two PCBs through their edge-mounted connection points in applications such as hard drives, motherboards, and industrial automation equipment. The L-Style is used when the boards are mounted side by side and require flexible connection along the boards’ long sides. The snap-in retention system ensures a secure connection and facilitates easy installation and removal.

The SQW-105-01-L-Q connector features a total of 1.2A current rating. The contact resistance between the contacts is also extremely low, with impedance values as low as 25 mOhms. This ensures minimal signal distortion. The working temperature range of the SQW-105-01-L-Q connector is -65°F to +150°F (-54°C to +66°C). The frequency range of operation is 0 to 4GHz.

The SQW-105-01-L-Q connector is a reliable and versatile electrical solution for board-level connections and delivers excellent signal integrity, robust enough to support the most demanding data applications. Other features include a low mating height (~15mm), a snap-in retention clip, and a shunt-type external shield to guard against EMI interference.

The SQW-105-01-L-Q connector is an ideal solution for applications where small size and high-frequency transmission are the most critical factor. The connector can be found in a variety of products, including computers, communication systems, automotive and industrial control systems, power equipment, and consumer electronics. When using the SQW-105-01-L-Q connector, users can be assured of reliable connections and efficient signal transmission.
