Resistor Networks and Voltage Dividers

Today, designers of circuits are demanding voltage dividers that approach the ideal in performance: stable, high speed, high accuracy components that will operate with assured, predictable reliability for years in a variety of environments. Vishay Foil voltage dividers and resistor networks are meeting those demands and add the dimensions of convenience and economy to resistor needs. Our long experience relieves the circuit designer of the complicated, costly and wasteful procedure of calculating the value of individual resistor components, ordering and then stabilizing, aging or matching these units, and literally assembling and testing his own resistor arrays. The Vishay Foil Resistors approach to dividers is simple and straight-forward, our solution consists of any combination of resistors, and the end result is what matters. As a consequence, the only data we require from the designer is the overall electrical performance specifications, the environment operational, and the desired physical requirements
