Thin Film on Silicon 2QSP / 2NBS-XX3 Dual Terminator
General Information
Package Schematic

9
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.
