PCB Mounted Jacks meet and exceed Category 6a requirements.

Press Release Summary:

Able to be specified for use in premise wiring systems and 10GBASE-T applications, SS-60300 Series has internal compensation and meets/exceeds 500 MHz Cat 6a requirements. Design integrates capacitive and inductive compensation on flexible circuit board that attaches directly to tips of jacks' contacts, canceling NEXT crosstalk introduced to jack from plug. FCC- and RoHS-compliant, vertical or right-angle products come in shielded and unshielded versions.

Stewart Connector's New Cat 6A PCB Mounted Jacks for Premise Wiring and 10-G Ethernet Applications

Internally Compensated Jacks Require Minimal Secondary Compensation To Promote Shorter Design Cycle and Minimize PCB Complexity and Cost

Glen Rock, PA, January 15, 2007...Announced today by Stewart Connector, a division of Bel Fuse Inc. (NASDAQ: BELFA & BELFB), is the availability of the SS-60300 Series of Category 6a PCB mounted jacks. The new CAT 6a jacks are the latest addition to Stewart Connector's expanding portfolio of connectors specifically designed to satisfy the demands of emerging high-speed networking and computing applications. Engineered to meet and exceed the 500 MHz requirements of the CAT 6a specifications, the jacks feature internal compensation to enhance electrical performance without the need for extensive secondary compensation on the main PCB. The Series boasts a patent-pending design, which integrates the capacitive and inductive compensation on a flexible circuit board that attaches directly to the tips of the jacks' contacts, close to where the jack and modular plug interface. The proximity of this flexible board to the connection helps cancel NEXT crosstalk introduced to the jack from the plug. Moreover, as the flexible circuit board attaches to the jacks' contacts, the jacks preserve the standard modular connector design to ensure durable and reliable connections.

Stewart's newest FCC and RoHS-compliant parts may be confidently specified for employment in premise wiring systems, and 10GBASE-T (10 Gigabit Ethernet over twisted-pair copper cabling) applications. They are most commonly used in wall outlets throughout buildings to connect computers, printers and varied peripheral equipment to networks. Jacks are equally appropriate for employment on patch panels at the consolidation points where buildings' network cables interconnect.

These PCB mountable components are offered in vertical or right-angle configurations, and in shielded and unshielded versions to afford engineers the utmost in design flexibility. Manufactured of UL94-V0 polycarbonate, they are provided standard with selective gold-plated (50-microinch) contacts to ensure high-cycle life. Additional specifications include an operating temperature range of -40 degrees to +85 degrees C, and durability of 750 mating cycles. Voltage rating is 150 VDC, and current rating is 1.5 A @ 25 degrees C. For more information visit http://belfuse.com/Data/DBObject/Cat6aJacks.pdf.

Pricing for Stewart Connector's SS-60300 Series of CAT 6a PCB mounted jacks is $1.35 each in quantities of 5,000 for the unshielded version. While delivery is 4 weeks, samples are immediately available for design-in quantities.
