It has a low insertion and extraction force, a low profile design, a low impedance, and excellent electrical and signal integrity qualities. Its ability to handle both high and low-speed data makes it ideal for many applications.

Application Field

QFS-078-04.25-L-D-TR is used in a variety of applications that require reliable and high-speed data connections between two boards in close proximity. It is commonly used in communication systems, computing equipment, metering systems, and automation and control applications. It is also used in data centers, networking devices, and embedded systems. Its low insertion and extraction force make it suitable for applications that require frequent access to internal components of the device.

Working Principle

QFS-078-04.25-L-D-TR connectors feature a two-piece design with an array of signal and power contacts mounted in a common housing. The contacts are arranged in an array that creates a row of exposed electrical contacts on both ends of the connector. The contacts are electrically connected to the board through surface mount technology, which eliminates the need for through-holes or solder connections. This keeps the installation process simple and allows the connector to be wired quickly and easily. The signal contacts of the connector are designed in a configuration that provides excellent signal integrity. These contacts have a low impedance and are capable of handling data rates up to 6 Gbit/s. The power contacts also have an excellent current carrying capacity. They are designed to handle up to 50A of current.

Conclusion

QFS-078-04.25-L-D-TR is a highly reliable, low-profile mezzanine board connector. It is designed to provide high speed and reliable signal and power connections between two boards in close proximity. Its low insertion and extraction force, low impedance, and excellent electrical and signal integrity qualities make it an ideal choice for many applications. Its ability to handle both high and low-speed data also makes it attractive for many applications.
