How is SMD Resistor Code Calculator: 3-Digit, 4-Digit, EIA-96 calculated?

Use 3 digits: R = first 2 digits × 10^(last digit) Ω. Decode 103, 1002, 4R7 and EIA-96 codes such as 01C. Distinguish decimal markers, multipliers and lookup codes before selecting a replacement.

How do I calculate this example: 103?

10000 Ω = 10 kΩ. This is a calculated example under the model stated above; it is not a measured component specification.

Which units does SMD Resistor Code Calculator: 3-Digit, 4-Digit, EIA-96 use?

Ω, kΩ, MΩ. Convert prefixes before substituting values; keep the input and output units attached to every number.

Is EIA-96 code 01C equal to 100 Ω?

No. 01 selects 100 from the E96 table; C multiplies by 100. The result is 10000 Ω, or 10 kΩ.
