DESCRIPTION
Wirewound resistors are best suited for use in high power,
high current applications. The silicon cement lacquer
coating enables Z300-Cxx to withstand challenging high
voltage surge conditions.
Suitable ohmic value with desired surge voltage handling
can be selected using table “Minimum Resistance Value for
Handling Surge Voltage as per IEC 61000-4-5 (1.2 / 50 μs
Pulse)” on page 2. The ceramic meets the highest
requirements against mechanical resistance, thermal
shocks, dielectric strength, and insulation resistance at high
temperatures. With different diameters and turn spacing's, a
large ohmic value range can be covered. The coating is
resistant to cleaning solvents specified in IEC 60115-1
(1)
.
The resistors are marked with resistance and tolerance.
Product quality is verified by testing procedures, performed
on all individual resistors. Resistance is measured on the
lead wires at a distance of 6 mm from the resistor body. If a
greater length of lead wire is used in the application, the user
may need to consider the additional wire resistance,
particularly with low resistance products.

ASSEMBLY
The resistors are axial leaded for soldering. The terminals of
the resistors are completely lead (Pb)-free, the special tin
plating provides compatibility with lead (Pb)-free and
lead-containing soldering processes.
Special lead forms may be available on request, please
inquire at
ww1resistors@vishay.com.
These components are high dissipation power resistors,
customers are advised to use a high melting point solder.
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. 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.

TESTS PROCEDURES AND REQUIREMENTS
All tests are carried out in accordance with the following
specifications:
• IEC 60115-1, generic specification (includes tests)
The test and requirements table contains only the most
important tests. For the full test schedule refer to the
documents listed above.
The tests are carried out with reference to IEC 60115-1, in
accordance with IEC 60068-2-xx test method and under
standard atmospheric conditions in accordance with
IEC 60068-1, 5.3.
A climatic category 40 / 200 / 56 is applied, defined by the
lower category temperature (LCT = -40 °C), the upper
category temperature (UCT = 200 °C), and the duration
of exposure in the damp heat, steady state test (56 days).
Unless otherwise specified the following values apply:
• Temperature: 15 °C to 35 °C
• Relative humidity: 45 % to 75 %
• Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
For performing some of the tests, the components are
mounted on a test board in accordance with IEC 60115-1,
4.31.
In test procedures and requirements table, only the tests
and requirements are listed with reference to the relevant
clauses of IEC 60115-1 and IEC 60068-2-xx test methods.
A short description of the test procedure is also given.
