Vishay Intertechnology Introduces New Power Metal Strip(R) Resistor Featuring Wide Side Terminal Construction for High 2 W Power

Vishay Intertechnology Introduces New Power Metal Strip(R) Resistor Featuring 
Wide Side Terminal Construction for High 2 W Power Rating
and Extremely Low Resistance Values Down to 0.003 Ohms in Compact
1020 Case Size 
MALVERN, PA -- (Marketwire) -- 03/25/13 --  Vishay Intertechnology,
Inc. (NYSE: VSH) today announced a new surface-mount Power Metal
Strip(R) resistor featuring a wide side terminal construction that
yields a high 2 W power rating in the compact 1020 case size. The
WSL1020 combines its high power-to-footprint-size ratio with
extremely low resistance values down to 0.003 ohms and stable
resistance tolerances to 0.5 %. 
The advanced construction of the Vishay Dale WSL1020 resistor
incorporates a solid metal nickel-chrome alloy resistive element with
low TCR (less than 20 ppm/ degrees C). This results in a high-power
resistor with an operating temperature range of - 65 degrees C to +
170 degrees C while maintaining the superior electrical
characteristics of the Power Metal Strip construction. 
The WSL1020 measures 0.200 in. by 0.100 in. [5.08 mm by 2.54 mm] with
a height profile of 0.025 in [0.635 mm]. The device's small size
allows for the design of high-power circuits featuring the smallest
possible resistor for higher-performance end products. Furthermore,
the WSL1020's high-temperature capability allows the use of the
resistor in harsh high-temperature environments without sacrificing
power rating or electrical performance.  
The resistor is ideal for all types of current sensing and pulse
applications, including switching and linear power supplies,
instruments, power amplifiers, and shunts in automotive electronic
controls such as engine, brushless DC motors, anti-lock brakes,
climate, and battery management controls; industrial controls,
including down-hole test/measurement equipment for oil/gas well
drilling; inverter controls for HVAC systems; and DC/DC converters
for servers, VRMs for laptops, and Li-Ion battery safety and
Like all Power Metal Strip resistors, the device released today
features an all-welded construction that contributes to its superior
electrical performance. A proprietary processing technique produces
extremely low resistance values ranging from 0.003 to 0.006 ohms,
with tight tolerances of 0.5 %, 1.0 %, and 5.0 %. The WSL1020
provides very low inductance of 0.5 to 5 nanohenries, an excellent
response to 50 MHz, and low thermal EMF (less than 3 microvolts/
degrees C). The lead (Pb)-free, RoHS-compliant device conforms to
Vishay "Green" standards.  
Samples and production quantities of the new resistor are available
now, with a lead time of 12 to 16 weeks for larger orders. Pricing
varies by application, volume, and region.
