Vishay Foil Resistors (VFR) is meeting those demands with the VFD244 of unequalled performance. VFR also adds the dimensions of convenience and economy to resistors 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 VFR 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 VFR requires is the overall electrical performance specifications, the environment operational, and the desired physical requirements. These four fundamental factors determine how “ideal” a precision divider resistor will be: 1. Initial absolute resistance value or how closely the absolute resistance value can be achieved 2. How precisely the value of individual resistors can be controlled 3. How precisely the end of life tolerance is maintained under a wide range of operating conditions and stress factors (temperature, humidity, load, etc.) 4. Fast response without ringing and fast thermal stabilization - and the ability of the resistor to react to rapid switching without adversely affecting the circuit function. Until the development of Vishay Foil resistors, precise control of all four factors was virtually impossible. Vishay Foil resistors are designed and manufactured to eliminate the inter-parameter compromise inherent in all other types of resistors. All important characteristics: tolerance, long term stability, temperature coefficient, power coefficient, ESD, noise, capacitance and inductance – are optimized, approaching the theoretical ideal in total performance. Resistor technologies before the development of Bulk Metal® Foil resistors all compromised the theoretical ideal performance in one or more ways. For example, the winding of wire and the evaporation or the sputtering of extremely thin metal each produce metallurgical changes in the resistance materials and these noticeably deteriorate the electrical characteristics. Such changes are not predictable, and thus randomly alter performance parameters. The form factor of other units also introduces losses in high frequency performance, limits power dissipation and prohibits size reduction.
