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 × 10Z
→ XY × 10Z Ω
The 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 × 103 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.
