Resistor value chart

Preferred Values or E-series The series looks as follows: 1– 1.2 – 1.5 – 1.8 – 2.2 – 2.7 – 3.3 – 3.9 – 4.7 – 5.6 – 6.8 – 8.2 – 10 etc. All of these values can be powers of ten (1.2 – 12 – 120, etc.). While the E12 series is the most common, other series are also available.

How do you find the value of a resistor?

The first two bands represent the digits or significant figures the third band indicates the

How do you read resistor color codes?

Therefore, the first three bands indicate the significant digits, the fourth band is the multiplication factor, and the fifth band represents the tolerance. For the example shown here: brown (1), yellow (4), violet (7), black (x 100 = x1), green (0.5%) represents a 147 Ω resistor with a 0.5% tolerance.

How do you read a 4 digit resistor?

Resistor Code Format Similar to the three digit EIA, the four digit format uses the beginning values to indicate the significant digits while the last digit is the multiplier. 'R' is used to indicate the position of a decimal point. The four digit format allows for higher precision.

What are the 4 types of resistors?

Types Of Resistors

Thermistors.
Varistor Resistors.
Photo Resistor or LDR (Light Dependent Resistors)
Surface Mount Resistors.

What are the most common resistor values?

Below are the common resistor values used in electronic circuit designs. They are the standard E3, E6, E12, E24, E48 and E96 resistor values. The E3 series resistors are the most widely used and hence these values will be the most common resistor values used within the electronics industry.

What is the value of 1 ohm resistor?

ohm defines the unit of resistance of "1 Ohm" as the resistance between two points in a conductor where the application of 1 volt will push 1 ampere, or 6.241×10^18 electrons. This value is usually represented in schematics with the greek letter "Ω", which is called omega, and pronounced "ohm".

What is a 1k resistor?

So, a 1k Ω resistor has a value of 1,000 ohms and the number we will code is 1,000.

What color is a 470 ohm resistor?

470 Ohm 2W High Quality Carbon Film Resistor (CFR) with ±5% Tolerance and Tin Plated Copper Leads. 470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden.

What do the numbers on resistors mean?

The Three and Four Digit Systems In these systems, the first two or three digits indicate the numerical resistance value of the resistor and the last digit gives a multiplier. The number of the last digit indicates the power of ten by which to multiply the given resistor value.

What is resistor coding?

Resistor Color Coding uses colored bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating.

What color is a 1K resistor?

A 1K Ohm resistor can be identified via resistor color codes of Brown-Black-Red-Gold or Brown-Black-Black-Brown-Gold.

How do you decode a 4 band resistor?

In the standard four band resistors, the first two bands indicate the two most-significant digits of the resistor's value. The third band is a weight value, which multiplies the two significant digits by a power of ten. The final band indicates the tolerance of the resistor.

What is the value of a 4 band resistor?

The values of color bands will be like this: Green = 5, Brown = 1, Violet = 7, Black = 100, Gold = 5%, Orange = 15ppm. Similar to the 3 band resistor, the first two bands always give the first 2 digits of the resistance value. The third band represents the multiplier while the fourth band represents tolerance.

What color is a 4 ohm resistor?

Color	Value
Red	2
Orange	3
Yellow	4

Which type of resistor is best?

Foil resistors are considered to have the best TCRs and precision of any resistor commonly available today. These low-noise components also have very low capacitance and no inductance at all.

Why resistor is used in circuit?

A resistor is a two-terminal electrical component that provides electrical resistance. In electronic circuits, resistors are predominantly used to lower the flow of current, divide voltages, block transmission signals, and bias active elements.

How do I know which resistor is which?

Hold the resistor with the closely grouped bands to your left and read the resistor from the left to the right. For 5% and 10% resistors 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 will never be silver or gold.
