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.
For non-standard technical requirements and special
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

It is a 1MHZ PWM signal. The 12V side is stepped down to 5V and fed to the microcontroller. It is found that the 5V power supply has more burrs, causing the PWM output waveform to be distorted. 12V 24...
