Polarized Capacitors
WARNING
REVERSE POLARITY OF ELECTROLYTIC & TANTALUM CAPACITORS CAN CAUSE
FIRE & EXPLOSION
Capacitors having a value of about 0.47 micro-farad or greater are often Electrolytic or Tantalum (polarized) types. This means that it is very important how they are connected. Polarized capacitors are almost always marked with the polarity on the body of the component. If the two capacitor leads are of different lengths then the longer of the two is usually the + (positive) terminal. Only non-polarized capacitors may be fitted to the breadboard or PCB either way, in the same way as resistors.
Surest way to damage an electrolytic capacitor is to reverse polarity at working voltage, self-destruction will occur and violent.
Use safety glasses and keep eyes and body parts away when applying power for the first time to a circuit that includes polarized capacitors. Discard any damaged parts.
General Capacitor Marking Table
IMPORTANT: Capacitors with values below 100 pf may be marked two ways: Either with just two digits (22 pF = "22") or three digits (22 pF = "220",). In the latter case the third digit signifies the number of zeros following the first two digits. "220" = 22 pF, "221" = 220 pF, "222" = 2200 pF.

Through-Hole Resistors
Four-color-band axial resistors
Main article: Electronic color code
Four-band identification is the most commonly used color coding scheme on all resistors. It consists of four colored bands that are painted around the body of the resistor. The scheme is simple: The first two numbers are the first two significant digits of the resistance value, the third is a multiplier, and the fourth is the tolerance of the value. Each color corresponds to a certain number, shown in the chart below. The tolerance for a 4-band resistor will be 1%, 5%, or 10%
5-color-band axial resistors
5-band identification is used for higher precision (lower tolerance) resistors (1%, 0.5%, 0.25%, 0.1%), to notate the extra digit. The first three bands represent the significant digits, the fourth is the multiplier, and the fifth is the tolerance. 5-band standard tolerance resistors are sometimes encountered, generally on older or specialized resistors. They can be identified by noting a standard tolerance color in the 4th band. The 5th band in this case is the temperature coefficient
SMT resistors
This image shows two surface mount resistors
Surface mounted resistors are printed with numerical values in a code related to that used on axial resistors. Standard-tolerance Surface Mount Technology (SMT) resistors are marked with a three-digit code, in which the first two digits are the first two significant digits of the value and the third digit is the power of ten (the number of zeroes).
For example:
"334" = 33 × 10,000 ohms = 330 kiloohms
"222" = 22 × 100 ohms = 2.2 kiloohms
"473" = 47 × 1,000 ohms = 47 kiloohms
"105" = 10 × 100,000 ohms = 1 megaohm
Resistances less than 100 ohms are written: 100, 220, 470. The final zero represents ten to the power zero, which is 1. For example:
"100" = 10 × 1 ohm = 10 ohms
"220" = 22 × 1 ohm = 22 ohms
Sometimes these values are marked as "10" or "22" to prevent a mistake.
Resistances less than 10 ohms have 'R' to indicate the position of the decimal point (radix point). For example: "R003" = 0.003 ohms. This is very small value, generally used in current sense applications.
"4R7" = 4.7 ohms
"0R22" = 0.22 ohms
"0R01" = 0.01 ohms
Precision resistors are marked with a four-digit code, in which the first three digits are the significant figures and the fourth is the power of ten. For example:
"1001" = 100 × 10 ohms = 1 kiloohm
"4992" = 499 × 100 ohms = 49.9 kiloohm
"1000" = 100 × 1 ohm = 100 ohms
"0", "000", and "0000" sometimes appear as values on surface-mount zero-ohm links, since these have (approximately) zero resistance.

An overcurrent event or fault is when the current (amperage) in an electrical circuit exceeds the rated capacity. There are many possible sources for an overcurrent fault such as a short, power cross, surge, etc. These faults can permanently damage the follow-on electronics and may cause serious injury.

SMD devices are, by their very nature, too small to carry conventional semiconductor type numbers. Instead, a somewhat arbitrary coding system has grown up, where the device package carries a simple two- or three-character ID code. Download SMD Code Cookbook
