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

Last Digit of 12NC Indicating Resistance Decade

Historical 12NC Example

• The 12NC for a VR25, resistor value 7.5 M

Ω, 5 %

tolerance, supplied on a bandoleer of 1000 units in

ammopack, is: 2322 241 13755.

• The 12NC for a VR37, resistor value 7.5 M

Ω, 5 %

tolerance, supplied on a bandoleer of 1000 units in

ammopack, is: 2322 242 13755.

• The 12NC for a VR68, resistor value 7.5 M

Ω, 5 %

tolerance, supplied on a bandoleer of 500 units in

ammopack, is: 2322 244 13755.
