COMPONENT MARKING
(Note: no marking on 0402 case size parts).
1. For
E-24
Series J (±5%) Tolerance In 0603, 0805, 1206, 2010 and 2512 sizes:
3 DIGIT SYSTEM - First two digits are significant and third digit is multiplier
Examples: 100 = 10 ohms
101 = 100 ohms
102 = 1,000
103 = 10,000 ohms 104 = 100,000 ohms
105 = 1,000,000 ohms
2. For
E-96
Series F (±1%) Tolerance in 0805, 1206 and 2010 and 2512 sizes:
NRCW Series
4 DIGIT SYSTEM - First 3 digits are significant and fourth digit is multiplier, "R" represents decimal point
Examples: 10R0 = 10 ohms 1000 = 100 ohms
1001 = 1,000 ohms 1002 = 10,000 1003 = 100,000 ohms
1004 = 1,000,000 ohms
