VSR144
Vishay Foil Resistors
Bulk Metal
®
Foil Technology Industrial Grade
Miniature Voltage Divider with TCR Tracking of
1.5 ppm/°C and Ratio Stability of 0.001 % (10 ppm)
FEATURES
Temperature coefficient of resistance (TCR):
absolute: ± 4 ppm/°C (0 °C to + 60 °C)
± 8 ppm/°C (- 55 °C to + 125 °C,
+ 25 °C ref.)
tracking: 1.5 ppm/°C
Tolerance: absolute and matching to ± 0.01 %
Resistance range: 100R to 20K per resistive element
The VSR144 is an industrial version of the 300144. This
device has the stability that is inherent in foil but does not
offer the tight match, TCR, or TCR tracking of the 300144.
This product is quite satisfactory for most industrial purposes
and should be considered when the total performance of the
300144 is not necessary.
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)
Power rating: 0.2 W at 70 °C, for the entire resistive
element R
1
and R
2
, divided proportionally between the two
elements
Load life ratio stability: < 0.001 % (10 ppm) 0.2 W at 70 °C
for 2000 h
Maximum working voltage: 200 V
Electrostatic discharge (ESD) up to 25 000 V
Non-inductive, non-capacitive design
Rise time: 1.0 ns effectively no ringing
Current noise: 0.010 µV
RMS
/V of applied voltage (< - 40 dB)
Thermal EMF: 0.05 µV/°C typical
Thermal stabilization time < 1 s (nominal value achieved
within 10 ppm of steady state value)
Voltage coefficient: < 0.1 ppm/V
Non-inductive: < 0.08 µH
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
