Ground termination with dampened resonance

摘要

A system of dampening resonance is provided. In an embodiment, ground traces may be coupled to a common or ground plane via dampening elements such as resistors a predetermined distance from a non-dampened coupling. Ground terminals in a connector have with a separated electrical length that allows for a potential to exist between the ground terminal and a common ground. When the ground terminals are coupled to the ground traces, the dampening element, which may be a resistor, helps convert energy traveling over ground terminal into heat, thus reducing or preventing resonance conditions in the connector.
