Product details
Carbon Film Resistors 0.25W
The RS PRO series of carbon film axial leaded resistors offer excellent long term stability and feature standard solder-plated copper leads. The carbon film is the most common axial leaded resistor which is used for applications where a very good tolerance and temperature coefficient are not necessary.
Features
Available in resistances from 1 Ohm to 9.1 mOhm
0.25W power rating
5% tolerance
Resistor body 2.3 mm in diameter, 6.3 mm in length
Carbon film construction
Long-term stability
Solder plated copper leads
Benefits of Carbon Composition
Carbon composition resistors are made from a moulded carbon powder that has been mixed with a phenolic resin to bind and create a uniform resistive body. It is then surrounded in an insulating case after attaching end leads.
Carbon composition resistors are used in applications in which the initial tolerance does not need to be any closer than +/- 5% of the value.
What does the power rating mean?
The power rating of a resistor describes the amount of power that the resistor can dissipate safely.
What do the colours mean?
Each of the colour bands has a specific meaning. The first two colours give the base value of the resistor, the next gives the multiplier and the final band the tolerance. If a resistor has five bands, it is a more precise resistor, in which the first three bands represent the base values, and the fourth and fifth represent the multiplier and tolerance respectively.
