Backplane Connectors - Hard Metric, Standard, are designed for high-speed, ultra-high speed, and data-intensive signal applications to ensure high performance connectivity. The 5646990-1 is one of the many connectors designed for these applications. It has a similar design to other hard metric connectors, which feature a linear contact arrangement with a uniform contact orientation, making it great for signal integrity.

The 5646990-1 is a 50–position connector component with a 0.8mm centerline spacing, and a 0.4mm contact pitch. It provides a board-level I/O connection for embedded designs in telecom boards, storage devices, and other applications. It supports a maximum of 4-pair differential signals per line. For added flexibility, this connector is available in multiple product forms, such as a hybrid card-edge connector with independent and differential leads, a card-edge connector with differential leads on both sides, a surface mounted circular connector with independent leads, and a board-to-board connector with independent or differential leads.

The 5646990-1 uses a modular design that provides uniformity and scalability across different product forms, maximizing efficiency in the development cycle. Its accessory design simplifies the mating of multiple connector component pieces, and its unique design allows it to accommodate the increased number of positions.

In terms of electrical performance, the connector has an excellent high-speed signal integrity performance due to its small contact pitch, which reduces impedance mismatch. Additionally, it has an excellent shock and vibration resistance. The reduced centerline contacts help improve signal integrity, which minimizes interference even in the most demanding environments.

The 5646990-1 is RoHS compliant and can be assembled and unassembled up to 10 times without any issues. It uses gold plating and titanium oxide containing polyols for corrosion resistance, as well as for improved contact resistance and a longer life span. The contact springs are designed for ultimate strength and flexibility, and the connector has an anti-vibration feature to prevent accidental detachment.

In conclusion, the 5646990-1 is a reliable and cost-effective hard metric connector solution that provides high performance connectivity in a range of high-speed, data-intensive, and ultra-high speed applications. Thanks to its modular design, it offers great scalability and flexibility for different product forms, as well as an excellent electrical performance.
