1. Marking for 0603 case size is a three character code. The
code includes two characters to denote the value (based on 0603
Resistance Codes Table and a third character that denotes the
value multiplier (see multiplier codes table).
2. The 0805 and 1206 case sizes parts use the standard four
character marking metthod as shown in the examples below.
E-24 and E-96 series - ±0.5% (D), ±0.25%(C), ±0.1% (B) tolerances
4 DIGIT MARKING SYSTEM - First 3 digits are the signifi cant fi g-
ures, the 4th digit is the mulitplier. "R"= decimal point.
Examples: 0R10 = 0.10 ohms, 1R00 = 1.0 ohms, 22R1=22.1
ohms, 3320= 332 ohms, 4751=4.75K ohms, 1132=11.3K ohms,
6493=649K ohms
