**Note: This Page deals with standard through hole 4 band resistors.**

**Note:Resistor with 5 or more color bands are generally precision resistor of some type **

High tolerance resistors may have 3 bands for significant figures rather than 2, or an additional band indicating temperature coefficient,
military grade resistors may have a 5th band which indicates reliability.

**Note: To Determine Surface Mount Resistor Values**

Most surface mount resistors conform to a 3-digit or 4-digit code with many variations and more all the time.

The most common 3-digit SMD resistor the first 2 numbers represent the first 2 numbers in the answer. The third digit is the number of 0 you add after the first two digits.

For example: 223 is 22 000. Or 32,000 ohms. Or 320k.

222 = 22 00 = 2,200 = 2k2

473 = 47 000 = 47,000 = 47k

105 = 10 00000 = 1,000,000 = 1M = one million ohms

For resistors less than 100 ohms the third number is 0: 100, 220, 330. example 22 and NO zero's = 22 ohms.

there are some smd resistors with only two numbers 10, 22 and 33 = 10,22,33 ohms.
