12NC INFORMATION

• The resistors have a 12-digit numeric code starting with

2312

• The subsequent 4 digits indicate the resistor type,

specification and packaging; see the 12NC table

• The remaining 4 digits indicate the resistance value:

– The first 3 digits indicate the resistance value

– The last digit indicates the resistance decade in

accordance with the 12NC Indicating Resistance

Decade table

Last Digit of 12NC Indicating Resistance Decade

12NC Example

The 12NC of a CMB 0207 resistor, value 47 k

Ω with ± 2 %

tolerance, supplied in blister tape of 2000 units per reel is:

2312 199 24703.

Notes

1. Products can be ordered using either the PRODUCT DESCRIPTION or the 12NC.

2. The PART NUMBER is shown to facilitate the introduction of the unified part numbering system. Currently, this PART NUMBER is applicable

in the Americas and in Asia/Pacific only.

3. Please refer to table PACKAGING, see below.

4. For CMB 0207 the temperature coefficient is not identified in the PRODUCT DESCRIPTION.
