INTRODUCTION

A manufacturer of the most precise production-size

resistors available, Vishay Foil Resistors (VFR) has

experienced the problems presented by virtually all

available conventional and specialized secondary

standards. Among these are: instrument accuracy,

resistance shifts caused by load, temperature or

environmental changes, difficulty in measurement of

last digits, limitation on usable frequency, size and ease

of setting.

From intensive analysis of these problems, VFR

has developed a complete new design. With the

unequalled combination of the Bulk Metal

Foil resistor’s

performances, Vishay Foil resistors offer accuracy,

stability and versatility never before combined in a

secondary standard resistor.

The FSR reduces these major problems to insignificance:

accuracy, resistance shift, frequency, and size.

Our Application Engineering department is available to

advise and make recommendations.

applications, please contact us via email.

Note

(1)

Measured by comparison against Vishay Foil Resistor

standards which are traceable to NIST.

•

Stability: ±0.0005% (5 ppm) at 25°C, 12 months

• No humidity effect: resistive element hermetically

sealed against moisture

• Small size and robust construction

• Direct plug-in device for most DMM’s available in the

market

• Each unit is supplied with certificate of accuracy

(1)

• RF shielded case

• Four terminal constructions with an additional

ground socket

•

Vishay Foil resistors are not restricted to standard

values; specific “as required” values can be

supplied at no additional cost or delivery time

(e.g., 1K23456 vs. 1K)

• Thermal stabilization time <1 s (nominal value achieved

within 10 ppm of steady state value)

• Electrostatic discharge (ESD) at least to 25 kV

• Rise time: 1 ns effectively no ringing

• Current noise: 0.010 μVRMS/V of applied voltage

(<-40 dB)

• Voltage coefficient: 0.1 ppm/V

• Non inductive: 0.08 μH

• Non hot spot design
