How to read Resistor Bands (para sa beginners)

[xlagi]

Most resistors have 4 colored bands printed on them that represent their resistance. Although resistors come in all different sizes and shapes, being able to read the bands will allow you to pick out your needed resistors faster (faster than picking up a random one and checking it with a multimeter until you get lucky).



If you look at a resistor (eg. the ones pictured above), you'll see one band off by itself, away from the other three. That is the right most band (the fourth band; the tolerance band). Starting from the left most band, each represents the following:

First Number
Second Number
Multiplier
Tolerance
From this, you can see that no resistor can have more than two significant digits. This means that you cannot have a 339 Ohm resistor by itself. In order to get that resistance, you would have to put smaller resistors in series. So, if your numbers come out to be 1, 0, 1k, and 1%, you have a 10k Ohm resistor (1% tolerance).

Here is the table needed to decipher the bands:

Color         First #           Second #             Multiplier Tolerance
Black           0                    0                            1 
Brown          1                    1 10                  +/- 1% (F)
Red             2                    2 100                 +/- 2% (G)
Orange         3                    3 1k 
Yellow          4                    4 10k 
Green           5                    5 100k                +/- 0.5% (D)
Blue             6                     6 1M                  +/- 0.25 (C)
Violet           7                     7 10M                +/- 0.1 (B)
Gray            8                      8 100M              +/- 0.05 (A)
White           9                      9 1000M


Additionally, there are three more possible tolerance bands:

Gold: +/- 5% (J)
Silver: +/- 10% (K)
None: +/- 20% (M)
Examples: (minus tolerance bands)
RED, BLUE, BROWN: [2], [6], [10] which means 26 x 10 = 260 Ohms
YELLOW, VIOLET, RED: [4], [7], [100] which means 47 x 100 = 4700 or 4.7k Ohms
YELLOW, YELLOW, YELLOW: [4], [4], [10k] which means 44 x 10k = 440k Ohms

ung colored bands ng resistor may pagkakahawig s colors of the rainbow...
roygbv w/o indigo.. then black brown s unahan and gray white s hulihan..

[bravokilo]

LAST PART OF THE COLOR CODE(BLUE,VIOLET,GREY,WHITE)" BUT VIRGINS GO WILD"

OK BAD BOYS, LETS GO BACK TO ELECTRONICS!

yan tulong sau yan, yung 3 color if 4 band multiplier siya, sa 5-6 band yung pangalawa sa huli ang multiplier, yung sa una, ididikit  mo lang ang mga number. bawat color meron value, idownload mo yung chart niya. tapos yung huli, tolerance siya

[ece.lourence]

para saan po ang tolerance, tinanong ko dati sa circuits2 prof ko sabi nya dapat alam mo na yan, tinuro dati sa circ1 or physics2 yan, ayaw sabihin sa akin.

[Positron E+]

pagkakaalam ko, nun bumuo ako ng amplifier, yan yung accuracy


ex. 1% tolerance brown kulay, meron pang violet etc.,

karamihan sa binbenta dito sa pinas 5% gold kulay, meron rin 10 % silver pero  kung nawawala yung kulay ng tolerance ex. talo lang yung kulay ibig sabihin nun 20% 

[rdpzycho]

tolerance 'yung range ng value ng isang resistor. say 100 ohms 5% tolerance, ang pwedeng actual value niya ay mag-range from 95 to 105 which is 100 +/- 5%.

[updated]

kapag 6band po ang clor code, 1st 3 band po ay yung value, 4th multiplier, 5th tolerance at yung 6th po ay temperature coefficient.

ito rin iniisip ko pag kinukuha ko ang value ng resistors.. hehe..

[Kaizer03]

dagdag nyo na rin yung 5bands..

and sa capacitors.. para references sa mga gustong malaman ito=) though masesearch mo naman sya.. and masasagot na rin ni wikipedia.. pero masmaganda kung masdiscussions kayo dito with reference=) that will be a great help lalo na sa mga nahihirapan o nalilito pang magbasa=)

[onahd_888]

Wow.. ok na re-fresh ako. nakalimutan ko na ito.
Thanks mga kapatid...
