Vishay Foil Resistors

Precision, Low Value, Current Sense/Current Shunt Resistors

Any value available within resistance range

INTRODUCTION

Model VCS101, VCS103 and VCS401 resistors are available

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

contact us.
