In this case, the first two bands indicate the two significant digits of resistance. The third band is used to indicate the multiplier. Resistor Band Colors As shown above, a carbon-composition resistor can have 4 to 6 bands. Our free resistor color code calculator makes it even simpler. Select the 4-band resistor type and don't enter anything in the field designated for the 4th band. This gap helps in resolving the reading direction.
We have three significant digits 150. The warnings are there for your information only and do not always imply that the resistor is was read the wrong way -- see the notes below. Generally the sixth band represents temperature coefficient. Therefore, when in doubt and when it's possible don't hesitate to use your trusted, old friend -- the -- to double-check the critical components. This packaging allows the zero-ohm resistor to be placed on the circuit board using the same equipment typically used to place other resistors. There are also E96 and E192 series for higher precision resistors, and of course manufacturers offer other values as they see fit.
The third figure is a letter used to indicate the multiplier. When you see the color selector box, click on the appropriate color bands. Example: Bad Beer Rots Our Young Guts But Vodka Goes Well — Get Some Now. The brown band tells us this resistor has a tolerance of 1%.

Next, you will be asked to enter the resistance and units e. Here you are at our site, contentabove 17 Resistor Color Code Chart Pdf published by at.
But there are some rules you can follow: 1. In a four-band system, the first two bands represent the significant digits, the third band is the multiplier, and the fourth band is the tolerance. The temperature coefficient is the last wider band in the 6 band code. The tolerance interval of a resistor is calculated by a of the theoretical value. As we can see, this is pretty darn close to the expected value.
What is its resistance and tolerance? Now we've pushed that boundary a little further. Therefore the first three bands are used to indicate the first three significant values of resistance. For the 10% resistors, there is the E24 series with twice as many standard values per decade, and E48 for the 5% resistors. With 5% and 10% resistors the procedure is simple: hold the resistor with the silver or gold band to the right and read the resistor from the left to the right. The first band can't be silver or gold, so if you hold such a resistor you'll know instantly where to start. All you have to do is enter the 3 digit code standard tolerance or 4 digit code precision surface mount that is found on the resistor and the calculator will automatically display the resistance value. If you want to find out the color bands for a value, use the tool on the left.

This indicates how much the actual resistance value of the resistor changes when the temperature changes. For example if the colors on the resistor are in the order of Yellow, Violet and Red from left, then the resistance can be calculated as 47× 102± 20 %. And now, this can be a 1st graphic: Symbols Gorgeous Band Resistor Color Code Calculator Bands Chart 5 from resistor color code chart pdf, source:indexxit. The third band is a multiplier, which tells us what to multiply the first two digits by to get the ohmic value of the resistor. Originally launched in 2011, it received over 5 000 000 downloads since.
. These resistors have one black band on them to represent zero ohms. That one goes: Big for black Beautiful brown Roses red Occupy orange Your yellow Garden green But blue Violets violet or purple Grow gray Wild white So silver GetSome gold. The fourth multiplier band is 1. The third band is the multiplier band and color-codes are as Black is 1, Brown is 10, Red is 100, Orange is 1000 1 K , Yellow is 10,000 10 K , Green is 100,000 100 K and Blue is 1,000,000 1 M. Hold the resistor with the closely grouped bands to your left and read the resistor from the left to the right.
They are all set for down load, if you like and wish to take it, simply click save badge in the page, and it will be instantly down loaded in your laptop computer. In the figure below, we see that the brown band on the left is the one closest to one end of the resistor and therefore the one we start with when determining its value. Ex 2: The colors on the five-band resistor are: red, red, green, gold, brown. The first three numbers indicate the significant value of the resistance and the fourth number indicates the multiplier. Resistor manufacturers adopted this color code.
Color Band1 Color Band2 Color Band3 Resistance Value:. The first two bands from the left are used to indicate the first and second significant digits of resistance. For the first and second colored bands, the values for Black is 0, Brown is 1, Red is 2, Orange is 3, Yellow is 4, Green is 5, Blue is 6, Violet is 7, Grey is 8 and White is 9. But how to identify which side is left. The program is free and is easy to use and install. To read a six-band resistor, we treat it just like a 5-band resistor with the 6 th band representing a temperature coefficient.
