# SMD resistor code 103- value in Ohms, formula

If you are looking for the value in ohm of smd** resistor code 103 **then you should refer images along with its notations below.

SMD resistors generally have markings on it. There are three coding systems for smd resistor:

- 3 digit SMD resistor coding system
- 4 digit SMD resistor coding system
- EIA96 SMD resistor coding system

The 3 digits general-purpose SMD shown below with code:

Lets the code printed on smd resistor be XYZ.

The general formula to calculate the value of smd resistor code of 3-digit in ohms,

**XYZ → XY × 10 ^{Z} **

**→ XY × 10**

^{Z}ΩThe first two digit in the code indicate the significant digits. And the 3rd one is a multiplier digit. This system is same as that of the resistor color code used in cylindrical carbon resistor large size we use. Here just numbers are used instead of colors.

## For calculating smd resistor code 103,

**Here,** X = 1 (1st digit)

Y = 0 (2nd digit)

Z = 3 (3rd multiplier digit)

103 → 10 × 1000Ω

→ 10 × 10^{3} Ω

→ **10kΩ **

So, it is **a 10k** smd resistor. By looking at this 3 digit code you can not guess the power rating of a resistor so you have to refer the datasheet by the component manufacturer/ provider.
