General Information

Dual Terminator networks are used to correctly terminate

single-ended SCSI bus lines. The standard R1, R2 combina-

tion ensures that the high frequency component of a signal

transition will see an impedance at the termination equal to

the characteristic impedance of the line. Fabricated with

Tantalum Nitride on Silicon, these resistors feature excellent

stability, TCR and tracking performance. The JEDEC

standard miniature packages offer the most space-efficient

Dual Terminator resistor array available.
