The GWS series, with completely welded construction, is
the perfect choice for high continuous power dissipation up
to 500 W with the option for adjustable (GWS E) and
non-inductive (GWS Ni) types. The components of this
series are well suited for harsh environments and exhibit a
long lifetime. With their high pulse power capability, they are
the ideal choice as inrush current limiters. Typical
applications include but are not limited to drive systems,
power supplies, frequency inverters, AC and DC filters, and
snubber resistors. For a given application, requirements of
ohmic value, rated power, peak voltage, pulse shape, pulse
duration, termination style, and environmental conditions
may be submitted to recommend the most suitable product.
APPLICATIONS
• Inrush current limiter
• Capacitor charge / discharge
• Snubber resistor
• Brake resistor
• Filter resistor

DESCRIPTION
Vitreous wirewound resistors are best suited for the use in
demanding environmental conditions. Their rugged design
and durable coating enable these resistors to withstand
extreme environmental stress. The vitreous coating is
designed for high stability and a long lifetime in humid
environments. The coating is resistant to all cleaning
chemicals commonly used in the electronic industry.
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility. The winding is
done with specific materials on a specially developed fine
ceramic body (Al
2
O
3
). The ceramic used meets the highest
requirements against mechanical resistance, thermal
shocks, dielectric strength, and insulation resistance at high
temperatures. With different diameters and turn spacings, a
large ohmic value range can be offered. The glaze is fired
layer by layer several times at high temperatures (> 600 °C).
The resistors are marked with type, resistance, and
tolerance.
Product quality is verified by testing procedures, performed
on all individual resistors.
The GWS series meet single lot / date code packaging
requirements.

ASSEMBLY
The resistors are available with lug style terminals (SL style)
for soldering, multiple screw terminal options (SS style, SB
style, or SSB style) for mechanical and electrical fixing, or
fast plug terminals (FST style) for assembly / disassembly
processes. The terminals of the resistors are completely
lead (Pb)-free. The special tin plating used provides
compatibility with lead (Pb)-free and lead-containing
soldering processes.
3D-Models are available on request, please inquire at
ww1resistors@vishay.com.
Different mounting accessories are available for fixing, see
the datasheet:
www.vishay.com/doc?21015.
In case of the adjustable version, the slider should be only
moved after removal of voltage and sufficient loosening of
the screw.
APPLICATION INFORMATION
The power dissipation of the resistor generates a
temperature rise with respect to the ambient. The
permissible dissipation is derated for temperatures above
40 °C, as shown in the derating diagram, in order to avoid
overheating of the resistor. The heat dissipated from the
resistor may affect adjacent components, hence proper
clearance will be required in order to avoid overheating.
The resistive wire is hermetically encapsulated. All materials
used are non-flammable and inorganic according to
UL 94-V0.
These resistors do not feature a limited lifetime when
operated within the permissible limits. However, resistance
value drift increasing over operating time may result in
exceeding a limit acceptable to the specific application,
thereby establishing a functional lifetime.
MATERIALS
