High Ohmic/High Voltage Resistors
ORDERING INFORMATION
Ordering Code (12NC)
• The resistors have a 12-digit ordering code starting with
2322 242.
• The subsequent:
first digit for 1 % tolerance products (E24 and E96 series)
or 2 digits for 5 % (E24 series) indicate the resistor type
and packaging.
• The remaining digits indicate the resistance value:
– The first 3 digits for 1 % or 2 digits for 5 % tolerance
products indicate the resistance value.
– The last digit indicates the resistance decade.

Ordering Example
The ordering code for a VR37, resistor value 7.5 MΩ, 5 %
tolerance, supplied on a bandolier of 1000 units in
ammopack, is: 2322 242 13755.

Yellow and grey are used instead of gold and silver because
metal particles in the lacquer could affect high-voltage
properties.
OUTLINES
MARKING
The nominal resistance and tolerance are marked on the
resistor using four or five coloured bands in accordance with
IEC publication 60062 “Colour codes for fixed resistors”.
The length of the body (L1) 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 % or 5 %. The
values of the E96/E24 series are in accordance with “IEC publication 60063”.
