Resistor color code

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.

What are the colors on a resistor?

The colors brown, red, green, blue, and violet are used as tolerance codes on 5-band resistors only. All 5-band resistors use a colored tolerance band. The blank (20%) “band” is only used with the “4-band” code (3 colored bands + a blank “band”).

What are the 5 types of resistors?

Types of Resistors

Fixed Value Resistors. These are the predominant type of resistor configuration, and as the name suggests, they have a fixed resistance value.
Variable Resistors. ...
Resistor Networks. ...
Carbon Film Resistors. ...
Metal Film Resistors. ...
Wirewound Resistors. ...
Metal Oxide Resistors. ...

How do I read a resistor?

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

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 read a color code?

Hex color codes start with a pound sign or hashtag (#) and are followed by six letters and/or numbers. The first two letters/numbers refer to red, the next two refer to green, and the last two refer to blue. ... For example:

A=10.
B=11.
C=12.
D=13.
E=14.
F=15.

What color is a 50 ohm resistor?

Color	Value
Brown	100 ppm/ºC
Red	50 ppm/ºC
Orange	15 ppm/ºC
Yellow	25 ppm/ºC

Which is best resistor?

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.

What is a resistor symbol?

The ohm (symbol: Ω) is the SI unit of electrical resistance, named after Georg Simon Ohm. An ohm is equivalent to a volt per ampere.

Why resistor is used in circuit?

In electronic circuits, resistors are predominantly used to lower the flow of current, divide voltages, block transmission signals, and bias active elements.

What is a color coding?

Color coding is a visual reminder system to warn, inform and guide employees. OSHA assigns specific meanings to certain colors; therefore, colors can be a warning of a particular hazard or give information or directions. Color coding is considered highly desirable.

How do you identify a resistor type?

Most types of resistors are linear devices that produce a voltage drop across themselves when a current flows through them There are two basic types of resistors with linear properties namely fixed resistors and variable resistors.

What color is a 470 ohm resistor?

470 Ohm 0.5W High Quality Carbon Film Resistor (CFR) with ±5% Tolerance and Tin Plated Copper Leads. 470 Ohm Resistor Color Code: Yellow, Violet, Brown, Golden.

What color is a 100 ohm resistor?

The color code for the four bands 100 Ohm resistor is brown, black, brown, gold. Theoretically, the value of 100 Ω resistor is between 95 Ω to 105 Ω. In 4- and 5-band resistors, the last band indicates the resistor's tolerance value. It is Gold in this case, indicating a tolerance value of 5%.

What color is a 150 ohm resistor?

150 Ohm Resistor Color Code: Brown, Green, Brown, Golden. Resistance: 150 Ohm, Power Rating: 2 Watts, Approximate Maximum Current: 115mA .

What color is a 100K resistor?

100K Ohm Resistor Color Code: Brown, Black, Yellow, Golden. Resistance: 100K Ohm, Power Rating: 2 Watts (2W), Approximate Maximum Current: 4.47mA .

What is hex colour code?

A HEX color is expressed as a six-digit combination of numbers and letters defined by its mix of red, green and blue (RGB). Basically, a HEX color code is shorthand for its RGB values with a little conversion gymnastics in between.

What are the color numbers?

Color Numbers

#FF0000 means FF worth of Red, and no Green or Blue.
#0000FF means no Red or Green, and FF worth of Blue. ...
#FFFF00 means FF worth of Red and Green, and Blue. ...
#000000 means no Red, Green, or Blue. ...
#FFFFFF means full FF amounts of Red, Green, and Blue.

How do you read a 5 color resistor?

If the colors on a 5 band resistor is in this order: brown, green, red, blue and violet (as shown in figure). The values of color bands will be like this: Brown = 1, Green = 5, Red = 2, blue = 106, Violet = 0.10%.
