1 / 1 page Carbon Composition Resistors Type CBT Series Literature No. 1773192 Issued: 12-05 Dimensions are shown for reference purposes only. Dimensions are in millimetres unless otherwise specified. Specifications subject to change. www.tycoelectronics.com passives.tycoelectronics.com Key Features I Designed for Pulse Withstand I Range of Resistance Tolerances I Solid Carbon Composition I Low Cost, High Performance I Two Sizes Available I Wide Range of Resistance Values I Supplied Ammo Pack in boxes of 2000 Type CBT Series 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.
