MUNICH, Germany, 28 Nov. 2006. Providing design engineers with a network device designed for the termination of high-speed applications, TT electronics' BI Technologies Electronic Components Division has released a RoHS-compliant SCSI termination resistor network.
Designated the BB1020DTLF, the low-voltage differential (LVD) network is designed to terminate high-performance SPI-2 (Ultra2) and SPI-3 (Ultra3) bussed applications.
The BB1020DT Series networks feature 18 resistors with a nominal resistance of 475 ohm and 9 resistors with a nominal resistance of 121 ohm. Absolute tolerance is +/-1%, with TCR of +/-100ppm/degree C. Power rating is 1 Watt per network at 70 degrees C. Inter-lead capacitance is less than 0.1pF. And operating temperature range is -55 degrees C to +125 degrees C. BI Technologies will also produce devices outside these specifications to meet customer requirements.
The BGA network measures 0.20 inches by 0.45 inches, with solder balls on 0.05 inch centers. Each of the BB1020DTLF devices contains low-voltage differential termination for up to 9 lines. The termination network is surface mountable with automated pick and place equipment. The balls for the RoHS-compliant version utilize a copper core and are tin plated.
Typical pricing for the BB1020DTLF SCSI termination network is approximately $0.70 each in quantities of 10,000 pieces, with lead times from stock to 8 weeks.
