Table of standard resistor values

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.

What is a 5% resistor?

The above resistor has a tolerance of 5%. This means that its ohm value could be 5% greater or 5% less than its quoted value. The above resistor has a value of 1k (1000 ohms) and a tolerance of 5% - this means that its value could be between 950 ohms and 1050 ohms (1000 - 5% to 1000 + 5%).

What are E12 resistor values?

The E12 series has 12 values for each multiple of ten; it is used for resistors with 10% tolerance. The values are 10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82, then it continues 100, 120, 150 etc.

Is 51000 ohms a standard value for a 5% resistor?

51 k is a standard value.

What are the 4 types of resistors?

Types Of Resistors

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

What is r1 and r2 resistor?

Resistors in parallel have the same voltage across them. In the schematic below, r1 and r2 have identical voltages across them, but have different currents flowing through them. This configuration is also known as a current divider .

What color is a 4.7 K resistor?

A 4.7K Ohm resistor can be identified via resistor color codes of Yellow-Purple-Red-Gold or Yellow-Purple-Black-Brown-Gold.

Is a 1 or 5 resistor better?

If the tolerance ratings you are referring to is the last color band, then the resistors with the smaller tolerance value is much better… Like for example, a 1% tolerance is preferred than a 5% or 10% , since it is an indication of precision in resistance value..

What color is a 5.1 K Ohm resistor?

Value	First Color	Third Color
51	Green	5.1 k
56*	Green	5.6 k
62	Blue	6.2 k
68*	Blue	6.8 k

Are E12 and C7 the same?

The industry uses many terms for the same size: C7 / E12 / Candelabra Base Bulbs typically used for chandelier-type fixtures and decorative lighting.

What does E12 stand for?

Small Base Light Bulb The 12 in E12 stands the diameter of the screw base in millimeters, so an E12 light bulb has an Edison Screw base that's 12 millimeters in diameter. This is a really simple name for a simple base that is easy to remember. So the E is for Edison and the 12 is for 12-millimeters.

What is E12 mean?

E12 is a designation used for a type of lamp base used on a light bulb. You are likely familiar with E26 lamp bases - the standard screw-in lamp base, approximately 1-inch in diameter, commonly used in standard A19 lamps. E12 uses the same naming system as E26, whereby the letter "E" signifies an Edison screw base.

What is 47K ohm resistor?

What is 4.7K resistance?

4.7K Ohm Resistor Color Code: Yellow, Violet, Red, Golden. Resistance: 4.7K Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 7.29mA . Price: Rs 1.20 ~ 0.55.

How many ohms is a 4K7 resistor?

Vishay on their datasheets for example will state 4K7 = 4.7 k ohms - all very correct when we consider the 4K7 is a form of code.

How do I know which resistor to use?

A rule of thumb is to find a resistor with twice the power rating. Here I would choose a 250 mW resistor since those are the most standard ones. Usually, you can just use the cheapest resistor you can find with the correct power rating.

What are the 3 ratings of a resistor?

The power rating of a resistor can be determined by monitoring its package size. Typical through-hole resistors are available with ½W or ¼W ratings. But power resistors are actually available with power ratings on the resistor. For example; 3W, 5W & 25W power resistors are available with 0.1Ω, 2Ω, 3Ω & 22kΩ values.

What is the most popular resistor?

Resistor Types

The fixed resistor type is the most common resistor.
There are several variable resistor types, their general property is that the resistance value is adjustable. ...
Thermistors are resistors of which the resistance changes significantly when the temperature changes.

What does R1 R2 and R3 stand for?

For R1 Market type all the products.-One sales Employee. For R2 Market type all products are divided into 2 groups.- Two sales Employee. For R3 Market type all products are divided into 3 groups- Three sales Employee. For R4 Market type all products are divided into 4 groups.- Four sales Employee.

What does R mean on a resistor?

ResistanceEdit Resistors have the symbol on the right. Resistance is defined as the voltage developed across the resistor per ampere of current through the resistor. Resistance has a symbol of R measured in unit called Ohm which has a symbol Ω.
