All Pb-free parts comply with EU Directive 2011/65/EU (RoHS2)

Description

Model BB1020DT is a SCSI LVD termination network designed to terminate high performance SPI-2 (Ultra2) and

SPI-3 (Ultra3) bussed applications. Wide SCSI bus applications can be terminated with three BB1020DT net-

works and a linear regulator IC.

For use in high-speed SCSI bus applications, the BB1020DT utilizes thick film resistors on a ceramic substrate

with ball grid array (BGA) terminals. Resistors and solder balls reside on the same side of the ceramic substrate,

resulting in the absolute minimum stray capacitance and inductance.
