Sunnyvale, CA--October 21, 1996--Responding to increasing system clock speeds, Fujitsu Takamisawa America Inc. (FTA; Sunnyvale, CA) has improved the EMI/RFI shielding capability of its SCSI-3 input/output (I/O) connectors. The new shielding design enables system manufacturers to meet more stringent FCC regulations and does not affect the cost of the connector.
Conventional SCSI-I/O connectors consist of a stamped metal shell joined to a die-cast body by small tabs. However, there are slight gaps around these tabs that are large enough to permit the escape of shorter wavelengths generated by faster clock speeds. The new connectors, therefore, feature a seamless design that improves RFI and EMI shielding effectiveness by 7.6-10.2 percent.
Fujitsu extended the stamped shell over the entire face of the die-cast housing and moved the attachment holes to the extreme ends of the connector. When the connector is mounted to the host system, the chassis overlaps the gaps and blocks the propagation of EMI. The design also provides a continuous ground path from the cable assembly to both the chassis and printed circuit board, which ensures that any electrostatic discharge from the SCSI cable is grounded.
The EMI/RFI-improved SCSI-3 connector is available now from stock. It is priced at $3.12 per connector when purchased in 10,000-piece quantities.
Fujitsu also adopted the new shielding design for its line of Media Independent Interface (MII) connectors. Available from stock, the price for a 40-position socket MII connector is priced at $2.42 in 10,000-piece quantities.
