| Meta Title | Standard Resistor Values - RF Cafe |
| Meta Description | Standard base resistor values are given in the following tables for the most commonly used tolerances (1%, 5%, 10%), along with |
| Meta Canonical | null |
| Boilerpipe Text | Resistors are one of the four fundamental types of passive electronic components;
the other three are the
inductor
,
the
capacitor
, and the
memristor
. The basic unit of resistance is the ohm (Ω).
Standard base resistor values are given in the following tables for the most
commonly used tolerances (1%, 2%, 5%, 10%), along with typically available resistance
ranges. To determine values other than the base, multiply the base value by 1, 10,
100, 1k, or 10k.
Standard resistor values are calculated
using the simple formula given below. Round the results to the proper number of
significant figures (three for 1% and 2%, two for 5% and 10%). As the chart at the
right shows
(created in Excel)
, plotting the values
on a logarithmic scale results in a straight line due to the exponential in the
equation.
"Researchers at Hewlett Packard Labs, where
the first practical memristor was created, have invented a new variation on the
device - a
memristor laser
..."
Example:
 Calculations indicate the need for a 355 kΩ resistor
and a tolerance of 1%. Look in the 1% table and select the 35.7 value (the nearest
available standard value). Multiply by 10,000 to convert to 357 kΩ.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4Â kbps
while tying up your telephone line, and a lady's voice announced "You've Got Mail"
