The AC series is the perfect choice for general purpose
power applications. The AEC-Q200 qualified AC-AT series
is best suited for automotive applications. The robust silicon
cement coating can handle challenging ambient and
operating conditions. Typical applications include but are
not limited to energy meters, power supplies and
automotive electronics. For a given application,
requirements of ohmic value, rated power, peak voltage,
pulse shape, pulse duration, lead bending, and
environmental conditions may be submitted to recommend
the most suitable product.
Various lead forms are available such as RT (radial taped),
WSZ (Z-form), DK (double kink), EK (single kink) with defined
mounting pitch.

DESCRIPTION
Wirewound resistors are best suited for use in high power,
high current applications. The silicon cement lacquer
coating enables AC series to withstand challenging
operating and environmental conditions. The coating is
resistant to cleaning solvents specified in IEC 60115-1
(1)
.
Production is strictly controlled and follows an extensive set
of instructions established for reproducibility.
The winding is done with a specific material on a specially
developed fine ceramic body (Al
2
O
3
). The ceramic meets the
highest requirements against mechanical resistance,
thermal shocks, dielectric strength, and insulation
resistance at high temperatures. With different diameters
and turn spacings of resistive wire, a large ohmic value
range can be covered.
The resistors are marked with resistance, rated dissipation
(P
40
) 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.
Vishay Draloric
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 encapsulated by a protective lacquer
coating.
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.
