HISTORICAL 12NC INFORMATION
• The resistors have a 12-digit numeric code starting with
- 2322 241 refers to VR25
- 2322 242 refers to VR37
- 2322 244 refers to VR68
• 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
