3 DIGIT SYSTEM - First two digits are signicant and third digit is multiplier, “R” indicates decimal on values under 10 ohms.
Examples: R10 = .10 ohms 1R0 = 1.0 ohms 102 = 1k ohms 470 = 47 ohms
103 = 10k ohms 101 = 100 ohms 104 = 100k ohms 105 = 1 megohms
2. For E-96 Series (±1%-F Tolerance) in 0805, 1206 and 1210 sizes:
4 DIGIT SYSTEM - First 3 digits are signicant and fourth digit is multiplier, “R” indicates decimal on values under 100 ohms.
Examples: 0R10 = .10 ohms 1R00 = 1.0 ohms 10R0 = 10 ohms 1003 = 100 kohms
1000 = 100 ohms 1004 = 1 megohms 1001 = 1k ohms
