Vishay Thin Film resistor networks are designed to be used in either analog
or digital circuits. The use of thin film resistive elements within the network
allows you to achieve an infinite number of very low noise and high stability
circuits for industrial, medical and scientific instrumentation.
Vishay Thin Film resistor networks are packaged in molded plastic
packages with sizes that are recognized throughout the world. The rugged
packaging offers superior environmental protection and consistent dimensions
for ease of placement with automatic SMT equipment.Vishay Thin Film stocks
many designs and values for off-the-shelf convenience.

Schematics
Resistors with one pin common
01 Schematic
The 01 circuit provides nominally equal resistors connected between
a common pin and a discrete PC board pin. Commonly used in the
following applications:
Resistance Range:
10 Ω to 50K Ω
• MOS/ROM Pull-up/Pull-down • TTL Input Pull-down
• Open Collector Pull-up
• "Wired OR" Pull-up
• Power Driven Pull-up
• Digital Pulse Squaring
• TTL Unused Gate Pull-up
• High Speed Parallels Pull-up
Lead #1
Isolated resistors
03 Schematic
The 03 circuit provides nominally equal resistors isolated from all
others and wired directly across. Commonly used in the following
applications:
Resistance Range:
• "Wired OR" Pull-up
• Power Driven Pull-up
• Powergate Pull-up
• Line Termination
• Long-line Impedance Balancing
• LED Current Limiting
• ECL Output Pull-down
• TTL Input Pull-down
10 Ω to 50K Ω

05 Schematic
Dual-line terminator; pulse squaring
The 05 circuit contains pairs of resistors connected between ground
and a common line. The junctions of these resistor pairs are connected
to the input leads. The 05 circuits are designed for dual-line termination
and pulse squaring. Standard values are:
