Vishay Foil Resistors
Bulk Metal® Foil Technology High Precision Voltage Divider
Resistors with TCR Tracking to 0.5 ppm/°C and
Tolerance Match to 0.005 % (50 ppm)
FEATURES
• Temperature coefficient of resistance (TCR)
absolute: 2 ppm/°C typical
(- 55 °C to + 125 °C, + 25 °C ref.)
TCR tracking: 0.5 ppm/°C
• Tolerance: absolute and matching to 0.005 %
(50 ppm)
INTRODUCTION
• Power rating: 0.2 W at 70 °C, for the entire resistive
element R1 and R2, divided proportionally between the two
values
Why tight tolerance is important?
Why do users employ tight tolerance resistors? A system or
a device or one particular circuit element must perform for a
specified period of time and at the end of that service period
it must still be performing within specifications.
During its useful life it may have been subjected to some
hostile service conditions and it is no longer within purchased
tolerance.
• Load life ratio stability: < 0.005 % (50 ppm) 0.2 W at 70 °C
for 2000 h
• Maximum working voltage: 200 V
• Resistance range: 100R to 20K per resistive element
What is ratio?
• Vishay Foil resistors are not restricted to standard
values/ratios; specific “as requested” values/ratios can be
supplied at no extra cost or delivery (e.g. 1K2345 vs. 1K)
The ratio tolerances available in a divider are variable and
dependent on resistor technology. Bulk Metal® foil provides
the tightest ratio tolerance available.
• Electrostatic discharge (ESD) up to 25 000 V
• Non-inductive, non-capacitive design
• Rise time: 1 ns effectively no ringing
• Thermal stabilization time < 1 s (nominal value achieved
within 10 ppm of steady state value)
The tight resolution capability and overall stability of foil
resistors permit adjustment within the divider to ratio not
available with other technologies. Ratios in network form, in
a common package have a better chance of holding tight
tolerances than those formed in a discrete matched set by
sorting.
Molded foil 300144, 300145 resistors can be provided in a
tolerance as tight as 0.005 %. Theoretically, ratios such as
these can be made initially with other resistor technologies.
However, less stable products will not hold these tight ratios
tolerances over time and applied stresses like voltage and
temperature.
• Current noise: 0.010 µVRMS/V of applied voltage (< - 40 dB)
• Thermal EMF: 0.05 µV/°C typical
• Voltage coefficient: < 0.1 ppm/V
• Non inductive: < 0.08 µH
Vishay Bulk Metal foil dividers/networks 300144, 300145
hold their ratio tolerances under defined circumstances.
Networks with tight ratio tolerances and controlled tracking
extend the useful life of equipment, whether expressed as
mean-time-between-failures (MTBF) or service periods to
recalibration or end-of-life-cycle.
• Non hot spot design
• Terminal finish: lead (Pb)-free or tin/lead alloy
• Compliant to RoHS directive 2002/95/EC
• Prototype quantities available in just 5 working days
or sooner. For more information, please contact
foil@vishaypg.com
How to avoid thermal EMF?
When the resistor’s terminals and the resistive element are
made of dissimilar metals and two junctions are at a different
temperature, a voltage is produced which is called “thermal
EMF”.
• For better performances see 300144Z, 300145Z (Z-Foil)
datasheet
The level of voltage output is a function of the metals
involved and the differential temperature. The voltage
produced is either positive or negative depending on which
junction is considered as a reference point. Virtually all
resistive products have these metallic junctions. It is
presumed they will eventually be terminated to copper as a
final metallic combination and therefore copper is used as a
typical reference material.
300144, 300145 have the lowest thermal EMF’s because all
junctions have low microvolts outputs. Moreover,
construction of the resistive element is such that the input
and output junctions of the resistor are so close that the
temperature gradients between then is highly unlikely. These
design factors produce a divider with very low thermal EMF.
