Flexible <strong>Power</strong> Arrangements<br />
In contrast with other VRM interconnects where U-shaped<br />
contacts are used, in Mini CROWN EDGE connectors all<br />
power contacts are isolated from each other, allowing the<br />
design engineer flexibility in laying out multiple voltage<br />
rails and returns.<br />
Robust, Low-Profile Housing Design<br />
Mini CROWN EDGE connectors feature a low profile housing<br />
design that leaves more room for placement of components<br />
on the VRM board. Rigorous shock and vibration<br />
testing shows that the two latches used to hold the VRM<br />
are robust enough to safely hold 2U height modules.<br />
