Cemented Wirewound Resistors with Ferrules
FEATURES
• Excellent pulse load capability
• High operating voltage up to 7350 V
• Non inductive type (Ni) available
• Different caps options:
- GDK style with different inner threads
- GZK made from drawn brass, nickel plated
• Easy to change when mounted with spring clips
The ZWK series, with completely welded construction, is the
• Non-flammable according to UL 94-V0
perfect choice for high continuous power dissipation up to
150 W with the option for a non-inductive type (ZWK Ni).
With their extremely 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
as snubber resistors. Specific application requirements
(ohmic value, rated power, peak voltage, pulse shape, pulse
duration, termination style, and environmental conditions)
can be submitted to Vishay for a recommendation of the
most suitable product.

DESCRIPTION
Vishay Draloric
ASSEMBLY
The rugged design of cemented wirewound resistors
enables them to withstand extreme high pulses and makes
them well suited for use in high power / high current
applications. 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 (Al2O3). With different
diameters and turn spacings, a large ohmic value range can
be offered. The ceramic used meets the highest
requirements against mechanical resistance, thermal shock,
dielectric strength, and insulation resistance at high
temperatures. The cement coating is fired layer by layer
several times at high temperatures. The resulting cement
coating is resistant to the cleaning solvents specified in
The resistors are available with two different termination
styles.
The GDK style has machined caps made from brass material
CW608N which is plated with nickel. The standard internal
thread size is M4 acc. to DIN 13-1. For custom inner thread
sizes, contact: ww1resistors@vishay.com.
The GZK style has termination caps made from drawn brass
plated with nickel.
It is easy to install / replace these components with either
termination style if they are mounted with spring clips. For
details about mounting accessories offered, see the
datasheet: www.vishay.com/doc?21015.
For special windings or non-inductive (GWK Ni) versions,
please contact: ww1resistors@vishay.com.
IEC 60115-1 (1)
.
The resistors are marked with type, resistance, tolerance
and winding material.
3D-Models are available upon request, please contact:
ww1resistors@vishay.com.
Product quality is verified by testing procedures, performed
on all individual resistors.
APPLICATION INFORMATION

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, therefore proper
clearance is required in order to avoid overheating.
MATERIALS
Vishay acknowledges the following systems for the
regulation of hazardous substances:
• IEC 62474, Material Declaration for Products of and for the
Electrotechnical Industry, with the list of declarable
substances given therein (2)
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.
• The Global Automotive Declarable Substance List
(GADSL) (3)

RELATED PRODUCTS
The products do not contain any of the banned substances
as per IEC 62474, GADSL, or the SVHC list, see
www.vishay.com/how/leadfree.
Hence the products fully comply with the following
directives:
In higher continuous power applications and more
demanding environmental conditions, a vitreous coated
alternative like the GWK series might be suitable. See the
datasheet:
• 2000/53/EC End-of-Life Vehicle Directive (ELV) and
Annex II (ELV II)
“Vitreous Wirewound Resistors with Ferrules”
www.vishay.com/doc?21006
• 2011/65/EU Restriction of the Use of Hazardous
Substances Directive (RoHS) with amendment
2015/863/EU
For low ohmic values and rated dissipation up to 500 W,
there is the cemented coated ZBS series. See the
datasheet:
• 2012/19/EU Waste Electrical and Electronic Equipment
Directive (WEEE)
“Cemented Wirewound Resistors with Corrugated Ribbon”
www.vishay.com/doc?21011
Vishay pursues the elimination of conflict minerals from its
supply chain, see the Conflict Minerals Policy at
www.vishay.com/doc?49037.

PULSE HANDLING FOR SHORT PULSES
For single pulses up to 100 ms duration the following energy resistance chart can be used to calculate the energy a resistor can
handle. Look to the resistance value or the next higher value of the model you need and follow this row to the energy per ohm
column to the left. The energy per ohm value multiplied by the resistance value is the energy the resistor can handle for pulses
less than or equal to 100 ms. This energy divided by 0.1 s is the power the resistor can handle for 100 ms. For the power the
resistor can handle for 10 ms divide the energy by 0.01 s. The maximum pulse power is limited at 625 x rated power.
Do not use this chart for ZWK Ni styles. For more information and assistance please contact ww1resistors@vishay.com.
