1k8 resistor color code

While these codes are most often associated with resistors, then can also apply to capacitors and other components.

Resistor color code is a color code to indicate the resistance of that resistor. Resistor color code can be formed with 3, 4, or 5 color bands. Each band has their own number to form a resistance number. The body color doesn't have any meaning. The figure below shows the color coding of the 1. The color code of resistor with 4 bands will be with colors of the bands are Brown, Gray, Red and Gold. The color of the first band indicates the value of the first significant digit.

Notice how the first two colors in each row are the same, and the last color in each column is the same. The next band represents the multiplier or "decade".

The four band 1K resistor is one of the most common resistors in electronics. The 1k resistor color code allows us to quickly identify the resistance value and tolerance of a 1k ohm resistor. This band is almost always gold or silver, so it is usually easy to identify. Resistor color codes always have digits, followed by a multiplier, follower by a tolerance value. Band One — 1st Digit: This is the first digit of the resistance value.

The humble resistor is the lowest-cost component in our maker box, but it is also incredibly useful. These resistor color codes tell us exactly how many Ohms of current each unit handles. How do we read a resistor color code? Why are some resistor color codes four bands and others five bands? What resistor do I need for an LED? We answer all of these questions and give you the tools to quickly calculate the correct resistor for all of your projects. Resistors have no polarity, so they can be used in any orientation in a circuit. But to identify the correct resistor color code values we need to understand the colored bands on the resistor. On a typical four-band hobby level resistor, there are three colors in a group. These are the first, second significant figures and the multiplier.

The table below lists every resistor value of the E12 range of preferred values. With the sizes of resistors and other components shrinking or changing in shape, it is getting difficult to fit all of the color bands on a resistor. In the E12 range there are 12 "preferred" or "basic" resistor values, and all of the others are simply decades of these values:. The others are specially designed for temperature critical applications. You will notice that there are 12 rows containing the basic resistor values, and the columns list the decade values thereof. To keep the convention standard, R is used to represent 0. In this case, the third band is Red which corresponds to the number 2. The table below shows the color codes for the E12 and E24 preferred values. This method uses three numbers, sometimes followed by a single letter. The third color band represents a decimal multiplier by which the first two digits must be multiplied to obtain the resistance value of the resistor. The color of the first band indicates the value of the first significant digit. The figure below shows the color coding of the 1.

Resistor color code is a color code to indicate the resistance of that resistor. Resistor color code can be formed with 3, 4, or 5 color bands.

There are also E48 and E96 tables, which have even more values. Each band has their own number to form a resistance number. This is added to the right of the first digit from band one. The fourth band indicates the tolerance values. The first band is Brown, which corresponds to the value 1. The color of the second band indicates the value of the second significant digit. The others are specially designed for temperature critical applications. Therefore the digits from band one and band two are: They just add one more significant digit. This tells how accurate the resistance compared to its specification. The third color band represents a decimal multiplier by which the first two digits must be multiplied to obtain the resistance value of the resistor. You will notice that there are 24 rows containing the basic resistor values and the columns to the right list the decade values thereof. The next band represents the multiplier or "decade".
