Carbon Composition Resistors Key Features Type CBT Series Solid Carbon Composition Designed for Pulse Withstand Low Cost, High Performance Two Sizes Available Supplied Ammo Pack in boxes of 2000 The CBT series of resistors is constructed utilising solid carbon composition, which is the traditional medium for absorbing high energy pulses, in cases of high inrush current. These resistors have evolved over many years to have excellent pulse withstand capabilities, whilst remaining very stable. These improved characteristics have been achieved by prudent selection of materials of optimum physical properties and by advances in the manufacturing process.

Where the calculated rated voltage is higher than the limiting element voltage, the limiting element voltage must be applied.
