Unitized Resistor Networks are comprised of Vishay S102C
elements combined and molded into single units. This method
of making networks yields some important advantages that
should be considered where space is not a limitation and
maximizing performance is important. To begin with, the leads
that emerge from the package go directly to the resistance
element (or an internal PC board), so the possibility of thermal
EMFs is very low. Next, the value range of the elements is large
(1 ohms to 150Kohms in a single foil element) and they can be
combined for even higher values. Finally, these elements
possess all the good features of discrete Bulk Metal
®
Foil
resistors, plus the ability to be further sorted for TCR track and
absolute match before encapsulation. These networks make
excellent voltage dividers, bridges, and attenuators where
performance and stability are important.

(1) Typical is a designer's reference that represents 85% of
production. Most of the
∆R's
shown are maximums. To ensure
that all typical values are maximums a "burn-in" is required.
(2)
∆R:
absolute resistance change.
(3)
∆Ratio:
change in ratio between resistors within the
network package from before to after the specified test.
(4) Depending on construction and ratio value.
(5) Measured < 0.1ppm/V and within the measurement capability of
the equipment. Voltage coefficient is "essentially zero".
