What is the color code for a 1k ohm resistor

 Guide to the 1K Resistor Color Code

The 4 bands 1K resistor is one of the maximum not unusualplace resistors in electronics. Its recognition makes it perfect to assist analyze the resistor color code and it`s beneficial as a way to without difficulty apprehend them in projects.

The 1k resistor color code lets us speedy pick out the resistance price and tolerance of a 1k ohm resistor. In this article, we`ll cowl the way to study four-band, five-band, and six-band 1K resistors.

1K Resistor Color Bands

It`s crucial to comprehend that now no resistor color code longer all 4 bands correspond to the quantity of resistance in Ohms. The first 3 bands inform us that the resistor`s nominal price is one thousand Ohms, and the 4th band offers us the tolerance of the resistor.

Two Helpful Tips for Reading a Resistor:

1) Identify the 4th band first. This band is sort of continually gold or silver, so it’s also clean to pick out.

2) Look for the distance between the third and 4th bands.

2          2d Digit            Black   0

How To Read the 1K Resistor Color Code

Resistor color codes continually have digits, observed via way of means of a multiplier, followed via way of means of a tolerance price.

For a 4-band resistor, every band has a selected role:

Band One – 1st Digit:

This is the primary digit of the resistance price. The first band is brown, which corresponds to price 1.

Band Two – 2d Digit:

The 2nd digit of the resistance price. This band is black, which corresponds to the price of 0. This is delivered to the proper of the primary digit (from band one). Therefore the digits from band one and the band are 10.

Band Three – Multiplier:

Takes the digits and multiplies them via way of means of a price given via way of means of this band. The real multiplier is 10n, in which n is the price of the band color. In this case, the 1/3 band is purple which corresponds to quantity 2. Therefore the multiplier is 102 = one hundred. So the full price of the resistance given via way of means of the colors is 10 x 102 Ω = one thousand Ω = 1kΩ.

Band Four – Tolerance:

This gives the price of the tolerance for the resistor. The maximum, not unusualplace values are five% (distinct via way of means of a gold band), and 10% (distinct via way of means of a silver band). This instance makes use of a gold band, giving us a tolerance of five%.

The general resistance is therefore: 1kΩ ± five% Ω.

This approach that the real resistance price may be everywhere from 950 Ω to 1050 Ω.

If the fourth band is silver, which means that the tolerance is 10% and the full resistance is 1kΩ ± 10% Ω. The real resistance ought to be between 900 Ω and one thousand Ω.

You can use a multimeter to discover the real resistance, however, be aware that it’s going to additionally range barely with temperature. Multimeters are an incredible manner to test any resistors you aren`t certain of, simply make sure to observe sensible protection guidelines.

Band vs. five-Band vs. 6-Band 1K Resistor Color Code

You will possibly stumble upon five-band or maybe 6 band resistors for your trips in electronics.

Luckily, it’s far very clean to study five or 6 band resistors in case you already understand the way to study a 4 band resistor.

Band 1K Resistor Color Code

For 1K resistors with 5 bands, the primary 3 bands may be brown, black, and black (indicating one hundred) and the fourth band may be brown indicating a multiplier of x10.

Band Number Function          Color   Value

1          1st Digit           Brown  1

2          2d Digit            Black   0

3          third Digit         Black   0

four      Multiplier          Brown  x 10

five      Tolerance        Gold (or silver)            ± five%

Total Value:

one thousand ± five% Ω

four-Band Resistor      five-Band Resistor      6-Band Resistor

1st band          1st digit of resistance price     1st digit of resistance price     1st digit of resistance price

2d band           2d digit of resistance price      2d digit of resistance price      2d digit of resistance price

third band        Multiplier (x 10, one hundred, etc)      third digit of resistance price   third digit of resistance price

4th band          Tolerance (± %)          Multiplier (x 10, one hundred, etc)      Multiplier (x 10, one hundred, etc)

fifth band         N/A      Tolerance (± %)          Tolerance (± %)

sixth band        N/A      N/A      Temperature Coefficient R(T)

Band vs. five Band 1K Resistor

Four band resistors have bands for the price, one for the multiplier, and one for the tolerance. Five band resistors upload an additional band for the price.

band resistors have 3 bands for the price, one for the multiplier, and one for the tolerance.

The technique of reading the resistor is the same; begin with the fifth band, seeking out a small hole among the fourth and 5th bands. This may be the tolerance. Then pass the lower back to the primary 4 bands to calculate the resistance price.

Band Resistors

Six-band resistors are precisely like 5-band Printed circuit board in china resistors besides they have got an additional band to suggest the temperature coefficient, i.e. how awful lot the resistance will alternate with temperature.

In this case, the remaining bands (i.e. the 5th and 6th bands) ought to be intently spaced, with an opening among the fourth and 5th bands.
