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.
With Vishay Thin Film you can depend on quality products delivered on time
with service backing the product.
Isolated resistors
The 03 circuit provides nominally equal resistors isolated from all
others and wired directly across. Commonly used in the following
applications:
"Wired OR" Pull-up
Long-line Impedance Balancing
Power Driven Pull-up
LED Current Limiting
Powergate Pull-up
ECL Output Pull-down
Line Termination
TTL Input Pull-down
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:
VSSR1605 -R

Differential terminator
The 47 schematic consists of series resistor sections connected
between Vcc and Ground. Each contains 3 resistors of 2 different
resistance values. Standard values are:
VSSR20 and VTSR20 - R

Resistors with one pin common
The 01 circuit provides nominally equal resistors connected between
a common pin and a discrete PC board pin. Commonly used in the
following applications:
MOS/ROM Pull-up/Pull-down
Open Collector Pull-up
"Wired OR" Pull-up
Power Driven Pull-up
TTL Input Pull-down
Digital Pulse Squaring
TTL Unused Gate Pull-up
High Speed Parallels Pull-up
