Resistors resist the flow of
electricity and are very useful in supplying desired voltages to
other electronic components. The resistance of a resistor is
measured in Ohms ().
Please note that our Min Res resistors are
usually supplied with the 4-Band Code, but with an additional red
band to indicate the 50ppm temperature coefficient after the brown
1% tolerance band. This additional band prevents the code being
read backwards accidentally, since no value begins red, brown
(21—), in the event that the extra large space between the third
and fourth bands is hard to identify.
Most resistors are so small that it is
impossible to print their values on them using normal numbers.
Instead they are marked with a code of coloured bands. Resistors
with a tolerance of 5% and 10% are marked with 4 bands, while
higher precision types, such as 2%, 1% and better, may be marked
with 5 bands to allow for an extra digit of precision. |
