Thin Film on Silicon 2QSP / 2NBS -XX1 Isolated Resistors
General Information
Package Schematic
Isolated resistor networks are commonly used in digital
circuits where series resistors are required on the system
bus. Fabricated with Tantalum Nitride and Nickel Chromium
technology on Silicon, these resistors feature excellent
stability, TCR and tracking performance. This product series
is available in a range of miniature package types
conforming to JEDEC standards.
