The physical size for surface mount chip resistors and capacitors is shown in the graphic above. The standard EIA component designations are shown under the type heading. The common values for capacitors or standard wattage size for resistors are shown for each EIA component type. The smaller the physical part, the lower the inductance. Pick the smallest possible package size which still meets the design criteria. The table provides dimensions in mm, the 'Type' is the English designation. The 'type' used above are different for metric designations.

Other values are possible. Omite produces High Voltage Chip Resistors up to 50G. I see that SRT Resistor produces resistor up to 100T ohms, also high voltage.

The Failure Band is only used with Military specification resistors, use the link below to view resistor Mil Specs. The table above shows a 4-band resistor color code [not counting the failure rate band]. Five band resistor color codes are also possible, with the fifth band being used as another significant digit. It;s common to see these color bands on 5%, 10% and 20% resistors, how ever in many cases 1% resistors have the value printed on the device.

Fixed Resistor Types
Carbon Composition:
Wirewound: Heat-Sinked, Phenlic, Ceramic, Flameproof, Enamel, Silicone Coated
Film: Cermet, Carbon Film, Metal Film, Metal Oxide Film,

This page lists the resistors standard values for both 1% and 5% tolerance.
