Vishay Foil Resistors
Bulk Metal^® Foil Technology Power
and Current Sensing Resistors with TCR of 2 ppm/°C,
Tolerance to ± 0.01 % and power up to 10 Watts
Any value available within resistance range
The basic features of Vishay Bulk Metal^® Foil resistors; tight
resistance tolerance, fast response time, low TCR, and
exceptional long-term stability, are available for power-circuit
applications. Typical applications are non-inductive design,
current sensing applications, deflection amplifiers, constant
current power supplies, forced balance electronic scales,
graphic display computers, character generation on CRTs,
and electron beam controls.
Our Application Engineering Department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
