If you’ve worked with electronics for any period of time, you’re undoubtedly familiar with components like resistors. But when it comes to understanding the color codes used on resistors, many people can feel lost. In this article, we’ll explain the color codes used on 1206 SMD resistors, using the example of 100PCS 1206 SMD Resistor 5% 47ohm 470 47 Ohm 47R.
First, let’s start with what is meant by “1206 SMD.” SMD stands for “Surface Mount Device,” and refers to components that mount directly onto printed circuit boards. 1206 is a specific size code – it means that the resistor measures 1.2mm by 0.6mm (or roughly 0.05 by 0.02 inches).
Now, on to the color codes. The stripes of color on a resistor indicate its resistance value. For example, on a 1206 resistor like 100PCS 1206 SMD Resistor 5% 47ohm 470 47 Ohm 47R, there will be three color stripes. The first two stripes show the digits of the resistance value, while the third stripe indicates the multiplier.
In our example, the first stripe is yellow, which corresponds to the digit 4. The second stripe is purple, which corresponds to the digit 7. So far, we have 47 as the resistance value. But what about the third stripe?
The third stripe on a resistor indicates the multiplier, which tells us how many zeros to add to our resistance value. The multiplier is determined by the color of the stripe. In our example, the third stripe is orange, which corresponds to a multiplier of 10^3, or 1,000.
So, putting it all together, we have a resistance value of 47 (yellow and purple stripes) multiplied by 1,000 (orange stripe). This gives us a final resistance value of 47,000 ohms, or 47 kiloohms.
But wait – what about the 5% in the product name, 100PCS 1206 SMD Resistor 5% 47ohm 470 47 Ohm 47R? This refers to the tolerance of the resistor, or how closely the actual resistance value will match the stated value. A 5% tolerance means that the actual resistance value of the resistor may be as much as 5% higher or lower than 47 kiloohms.
One final note: it’s important to interpret the stripes on a resistor in the correct order. The first two stripes are read left to right (although the colors may be reversed from manufacturer to manufacturer), while the third stripe is read from right to left.
In summary, understanding the color codes on 1206 SMD resistors like 100PCS 1206 SMD Resistor 5% 47ohm 470 47 Ohm 47R is a key skill for working with electronics. By decoding the color stripes on the resistor, you can determine its resistance value and tolerance. With practice, you’ll be able to quickly and accurately identify resistors and incorporate them into your electronic projects.
