Ordering code (12NC)

• The resistors have a 12-digit
ordering code starting with 23.
• The first 7 digits indicate the resistor
type and packaging; see Tables 1 and 2.
• The remaining 3 digits indicate the
resistance value:
– The first 2 digits indicate the
resistance value.
– The last digit indicates the
resistance decade in accordance

Mounting

The resistors are suitable for processing on automatic insertion equipment and cutting and bending machines.

Marking

The nominal resistance and tolerance are marked on the resistor using four coloured bands in accordance with IEC publication 60062, “Colour codes for fixed resistors”.

Outlines

The length of the body (L
) is measured
1
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”).

TESTS AND REQUIREMENTS

Essentially all tests are carried out in accordance with the schedule of “IEC publication 60115-1”, category
LCT/UCT/56 (rated temperature range: Lower Category Temperature, Upper Category Temperature; damp heat,
long term, 56 days). The testing also covers the requirements specified by EIA and EIAJ.
The tests are carried out in accordance with IEC publication 60068-2, “Recommended basic climatic and mechanical robustness testing procedure for electronic components” and under standard atmospheric conditions according to “IEC 60068-1”, subclause 5.3.
