HyperJack™ is the trade name for Molex RJ45 jacks that include wirewound components (also called magnetics). The Molex HyperJack incorporates the magnetics for common mode rejection, DC insulation of cable side versus board side, possible transforming of the signal (PHY depending). It also incorporates resistors and/or capacitors to terminate noise from the non-used pairs and to cope with the DC share of the common mode noise of the signal pairs
High performance is needed when running LANs or WANs with Ethernet 10BaseT or 100BaseT transmission characteristics. HyperJack magnetic Jack is available in two connection types: Low and Standard Profile and Stacked Profile.
