Ruland Beam, 25mm Outside Diameter, 10mm Bore, 20mm Length Flexible Coupling

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.

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

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.

The power rating of a resistor describes the amount of power that the resistor can dissipate safely.

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.

RS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice. Trusted by engineers all over the world, every part of every RS PRO product has been rigorously tested against demanding industry standards; they’re only given the RS PRO Seal of Approval if we’re confident of their exceptional quality, which means you can be confident too.
