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.
Military Resistor Specifications are listed on this page: Resistor MIL Specs
Resistor manufacturers are listed on the Resistor page. Additional
manufacturers may be found by clicking the Components icons at the bottom
of the page. OEM resistor and electronic component distributors may be
found by hitting the Distributors icon below.
