Surface Mount Resistors

01 00 27 - 20 31 34 88 / 29 46 23 19
A 330k SM resistor

All SM resistors conform to a 3-digit or 4-digit code. But there are a number of codes, according to the tolerance of the resistor. It's getting very complicated. Here is a basic 3-digit SM resistor:

The first two digits represent the two digits in the answer. The third digit represents the number of zero's you must place after the two digits. The answer will be OHMS. For example: 334 is written 33 0 000. This is written 330,000 ohms. The comma can be replaced by the letter "k". The final answer is: 330k. 222 = 22 00 = 2,200 = 2k2 473 = 47 000 = 47,000 = 47k 105 = 10 00000 = 1,000,000 = 1M = one million ohms There is one trick you have to remember. Resistances less than 100

ohms are written: 100, 220, 470. These are 10 and NO zero's = 10 ohms = 10R or 22 and no zero's = 22R or 47 and no zero's = 47R. Sometimes the resistor is marked: 10, 22 and 47 to prevent a mistake. Remember: R = ohms k = kilo ohms = 1,000 ohms M = Meg = 1,000,000 ohms The 3 letters (R, k and M) are put in place of the decimal point. This way you cannot make a mistake when reading a value of resistance.

1101 = 1k1

Click to see the complete range of SM resistor markings for 4-digit code:

0000 is a value on a surface-mount resistor. It is a zero-ohm LINK! Resistances less than 10 ohms have 'R' to indicate the position of the decimal point. Here are some examples: Three Digit Examples Four Digit Examples

330 is 33 ohms - not 330 ohms 221 is 220 ohms

1000 is 100 ohms - not 1000 ohms

4992 is 49 900 ohms, or 49k9



683 is 68 000 ohms, or 68k 105 is 1 000 000 ohms, or 1M 8R2 is 8.2 ohms

1623 is 162 000 ohms, or 162k 0R56 or R56 is 0.56 ohms

A new coding system has appeared on 1% types. This is known as the EIA-96 marking method. It consists of a three-character code. The first two digits signify the 3 significant digits of the resistor value, using the lookup table below. The third character - a letter signifies the multiplier.

22A is a 165 ohm resistor, 68C is a 49900 ohm (49k9) and 43E a 2740000 (2M74). This marking scheme applies to 1% resistors only. A similar arrangement can be used for 2% and 5% tolerance types. The multiplier letters are identical to 1% ones, but occur before the number code and the following code is used:
