MMH21-0341JU is a kind of special backplane connector, which is designed for providing simple and reliable connections between different printed circuit boards (PCBs) in vertically mounted applications. It is capable of carrying up to 100 amperes and is capable of operating at high speeds while providing a high-frequency signal integrity. Backplane connectors are widely used in the fields of automotive, consumer electronics, communications, computing, and medical.

Application Field of MMH21-0341JU

MMH21-0341JU backplane connector is mainly used in industrial automation, data communications, power distribution system, and factory automation applications. Its high-speed and high-frequency signal integrity features make it ideal for use in applications such as server systems, data communication systems, video surveillance systems, industrial automation, and medical instrumentation. It is also suitable for use in low-profile applications, such as static SAN and memory systems. In addition, it’s perfect for use in double-sided PCBs and is capable of carrying more signal and power on both sides of the application.

Working Principle of MMH21-0341JU

The working principle of MMH21-0341JU is to convert electrical current input to electro-magnetic conduction for effective electrical connection. It utilizes the combination of electrical contact pairing and vias to provide a connection between the two PCBs. In addition, it features two non-conductive nuts or pins that serve as stand-offs on one side of the connection, which prevents the connection from shorting out. On the other side, the contact pins are arranged in a specific pattern that allows for maximum contact across both sides of the PCBs. This principle not only prevents the shorting of the connection, it also helps minimize both contact resistance and crosstalk across the two sides of the connection, allowing the connection to run at the highest speed possible.

The MMH21-0341JU connector also features a two-piece shielding system to further minimize the effect of external electromagnetic interference (EMI). This two-piece shielding system works by shielding the connection from external EMI on one side, while allowing electrical signals to pass through on the other side. This, combined with its high-speed and high-frequency signal integrity features, helps to provide more reliable connections over a wider frequency range when used in sensitive applications.

These features of the MMH21-0341JU connector make it suitable for use in a wide variety of vertical stack applications. Its use in these applications helps to reduce overall cost, prevent EMI interference, and improve signal integrity.
