How to Read the Codes

3-Digit Code Example: 472

First two digits (47) are the significant figures. Third digit (2) is the number of zeros to add.

472 = 47 + 00 = 4700 ohms = 4.7 kilohms

4-Digit Code Example: 4702

First three digits (470) are the significant figures. Fourth digit (2) is the number of zeros.

4702 = 470 + 00 = 47000 ohms = 47 kilohms

EIA-96 Code Example: 01C

Two-digit number (01) maps to the first E96 value (100). Letter (C) is the multiplier (x100).

01C = 100 x 100 = 10000 ohms = 10 kilohms

R Notation: 4R7

The R indicates the decimal point position.

4R7 = 4.7 ohms
