Improved resistors seem ideal for circuit protection

Low cost, high performance CBT25 (maximum voltage 250V) and CBT50 (maximum voltage 350V) resistors are constructed utilising a solid carbon composition – perfect for absorbing high energy pulses. A direct replacement for hot moulded carbon composition resistors, solid carbon CBT series resistors offer a much higher pulse handling capability because the entire rod conducts. For example, in case of a fast (<100ms), high-energy pulse, the conductive element is required to withstand all of the energy and absorb all of the heat generated.

Benefiting from their small size, a range of resistance tolerances and a wide range of resistance values (1R0 to 5M6 for the CBT25 model and 1R0 to 22M for the CBT50 model), improved CBT series resistors are designed for a very wide operating temperature range of -55 up to 125 degrees Celsius. The insulation resistance for both versions is 1000 M minimum. The devices are supplied ammo pack in boxes of 2000.
