VERY LOW OHMIC VALUE
To maximize energy conversion efficiency and minimize
power consumption, current sense resistors should be of the
lowest resistance value possible (typically below 25 mΩ).
The single Power Metal Strip resistor can achieve the same
low ohmic values for which four to six conventional cermet
chips or two or more conventional thin film chips are
required.

For maximizing the sensing performance and saving energy,
the tolerance of the sense resistor must be ± 1 % or tighter.
1 % tolerance allows designers to use a narrow resistance
window when specifying sensing voltages. Another
advantage of 1 % or better tolerance is reduced response
time to switching currents. The chart to the left shows that it
takes a compareable thick film resistor almost three times
longer than the Power Metal Strip to stabilize it’s sensing
voltage.

HIGH TEMPERATURE CAPABILITY
(UP TO + 275 °C)
% Power
When used in industrial and automotive applications,
components may be exposed to high temperatures. The
current sensing resistor must be capable of operating in high
temperature conditions with a minimal reduction (derating) of
rated power. The Vishay Dale WSL (maximum of 275 °C)
type resistors will withstand high temperatures much better
than cermet chips. The chart to the right provides a high
temperature comparison of these device types.

LOW TEMPERATURE COEFFICIENT OF
RESISTANCE (TCR) (DOWN TO 30 PPM/°C)
The low TCR of Vishay Power Metal Strip resistors
minimizes the resistance change caused by self heating and
high temperature environments.
This chart illustrates voltage of a 30 ppm/°C Vishay Power
Metal Strip® resistors compared to a typical 100 ppm/°C
metal strip and 700 ppm/°C thick film chip.

Temperature
Dissimilar metals, in contact with each other, produces a
small voltage. This voltage varies with temperature and is
therefore called a “Thermal EMF”, or “thermocouple effect”.
The rate of change of voltage with temperature from an
intermetallic junction is a function of the metallic combination
and the polarity of the voltage produced.
Virtually all resistors have intermetallic combinations and it is
presumed will eventually be connected to copper as a final
intermetallic junction (circuit trace). Hence, copper is typical
reference metal.

Thermal EMF is an important consideration in low value
resistors used in DC circuits. Thermal EMF can be large
enough, when compared to the expected signal, that it can
result in large sensing error. Vishay’s Power Metal Strip
current sensing resistors utilize resistance materials that
have low Thermal EMF characteristics (below µV/°C).

TERMINAL CONSTRUCTION
At resistance levels down to 1 mΩ and tolerance of 1 % or
larger, a two-terminal construction is typically acceptable.
Where better accuracy is required, Vishay recommends the
use of the four-terminal WSK2512 or WSL3637. The
four-terminal construction reduces terminal resistance,
copper terminal TCR, and solder joint TCR.

Multiple Package Sizes (0603 to 5931)
Vishay’s Power Metal Strip resistors are available in more
than 10 package sizes. Multiple package sizes give the
customer the ability to minimize PCB space by utilizing a
smaller component or lessen resistor temperature by utilizing
a larger component for their current sense applications.

HIGH POWER DENSITY (UP TP 120 W/IN2)
of up to 5 W. The WSL...-18, WSLP1206, WSR3, WSR5 and
WSH2818 resistors offer a high power-to-package size ratio
while maintaining superior electrical characteristics. These
high power ratings enable designers to use smaller PCBs,
which in turn increases manufactoring speed and reduces
raw material costs.
Vishay’s Power Metal Strip resistors have envolved to “High
Power“ WSL...-18, WSLP1206, WSR3, WSR5 and
WSH2818 type resistors. With the higher power capacity of
standard WSL and WSR2 type resistor series, the
WSL...-18, WSLP1206, WSR3 and WSH2818 series are
intended for high power, current sensing applications.
Specially selected materials permit these high power ratings
