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.

SALES

(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".

(6) 2 ppm when in hermetically sealed package.
