Today, designers of analog circuits are demanding
discrete power current sense resistors 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. Foil is
meeting those demands with the VCS232Z of unequalled
performances.
These four fundamental factors determine how “ideal” a
precision power current sense resistor will be:
1. Initial 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 Foil resistors, precise control of all
four factors was virtually impossible.
Foil VCS232Z resistor containing the latest version of Z-foil
achieves maximum stability, a near zero temperature
coefficient and the ability to remove errors due to
temperature gradients. This superior performance is built-in
for every unit and does not rely on culling or other artificial
means for uniform excellence.
