High Ohmic/High Voltage Resistors
DIMENSIONS
MARKING
The nominal resistance and tolerance are marked on the
resistor using four or five colored bands in accordance with
IEC publication 60062
“Color codes for fixed resistors”
.
Yellow and grey are used instead of gold and silver because
metal particles in the lacquer could affect high-voltage
properties.
OUTLINES
The length of the body (L
1
) is measured by inserting the
leads into holes of two identical gauge plates and moving
these plates parallel to each other until the resistor body is
clamped without deformation
(“IEC publication 60294”)

FUNCTIONAL PERFORMANCE
PRODUCT CHARACTERIZATION
Standard values of nominal resistance are taken from the E96/E24/E12 series for resistors with a tolerance of ±
1 %, 5 % or
10 %. The values of the E96/E24/E12 series are in accordance with “IEC publication 60063”.
Note
1.
The maximum voltage that may be continuously applied to the resistor element, see
“IEC publication 60115-1”
.
The maximum permissible hot-spot temperature is 155
°
C.
