INTRODUCTION
Model VCS101, VCS103 and VCS401 resistors are available
in 2 configurations. This Bulk Metal^® resistor can serve as a
low ohm, high power resistive shunt or as a medium power
current sensing resistor. Resistors are non insulated.
Our Applications Engineering Department is prepared to
advise and to make recommendations. For non standard
technical requirements and special applications, please
