Vishay Foil Resistors

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

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

contact us.
