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(R) 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.
