FEATURES

INTRODUCTION
The CSM3637Z is a low value current sense resistor,
providing power and precision in a four terminal, surface
mount configuration. Its all welded construction is made up
of a Bulk Metal ? resistive element with plated copper
terminations.
There are many current sense resistors on the market. Until
now the combination of very stable and precise resistors
with extremely low TCR as much as ± 5 ppm/°C maximum,
tight tolerance of ± 0.1 % and load life stability of ± 0.2 %
(2000 h, + 70 °C at rated power) was not easily available.
The key performance of the new CSM3637Z is its extremely
low TCR value.
These specifications are based on tests performed in
accordance with methods prescribed by appropriate
MIL-PRF standards (MIL-PRF-55342 and MIL-PRF-49465).
The four terminal device separates the current leads from
the voltage sensing leads. This configuration eliminates the
effect of the lead wire resistance from points A to B and
C to D.
In addition a key feature of the CSM3637Z is its low thermal
EMF design (very important for low ohmic value DC
applications). The welded terminals make intimate contact
with the chip thereby minimizing temperature differentials.
? Resistance range: 3 m Ω to 50 m Ω
? Temperature coefficient of resistance (TCR):
± 5 ppm/°C maximum
(- 55 °C to + 125 °C, + 25 °C ref.)
? Load life stability to ± 0.2 % (70 °C, 2000 h at
rated power)
? Power rating: to 3 W (see table 1)
? Resistance tolerance: ± 0.1 %
? Vishay Foil resistors are not restricted to standard values;
specific “as required” values can be supplied at no extra
cost or delivery (e.g. 10.2345 m Ω vs. 10 m Ω )
? Short time overload: ± 0.1 % typical
? Proprietary processing technique produces extremely low
resistance values with improved stability
? All welded construction
? Solderable terminations
? Very low inductance 0.5 nH
? Excellent frequency response to 50 MHz
? Low thermal EMF < 3 μV/°C (DC offset error, significant for
low values)
? Maximum current: up to 31 A
? Four terminal (Kelvin) design: allows for precise and
accurate measurements
? Terminal finish: lead (Pb)-free or tin/lead alloy
? Prototype quantities available in just 5 working days
