FEATURES
High pulse loading capability
Small size
Lead (Pb)-free solder contacts
Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
Compatible with "Restriction of the use of Hazardous
Substances" (RoHS) directive 2002/95/EC (issue 2004)
APPLICATIONS
Where high resistance, high stability and high reliability at
high voltage are required
High humidity environment
White goods
Power supplies
A metal glazed film is deposited on a high grade ceramic body.
After a helical groove has been cut in the resistive layer, tinned
electrolytic copper wires are welded to the end-caps. The
resistors are coated with a light blue lacquer which provides
electrical, mechanical, and climatic protection.
The encapsulation is resistant to all cleaning solvents in
accordance
with
“MIL-STD 202E,
“IEC 60068-2-45”.

12NC INFORMATION
The resistors have a 12-digit numeric code starting with
2322 241
The subsequent:
first digit for 1 % tolerance products (E24 and E96 series)
or 2 digits for 5 % (E24 series) and 10 % (E12 series)
indicate the resistor type and packing.
The remaining digits indicate the resistance value:
– The first 3 digits for 1 % or 2 digits for 5 and 10 %
tolerance products indicate the resistance value.
– The last digit indicates the resistance decade.
Last Digit of 12NC Indicating Resistance Decade
12NC Example
The 12NC for a VR25, resistor value 7.5 M
, 5 % tolerance,
supplied on a bandolier of 1000 units in ammopack, is:
2322 241 13755.
