4 / 10 page Varistor Products ©2010 Littelfuse, Inc. Revision: September 9, 2010 C-III Varistor Series Radial Lead Varistors > C-III series Specifications are subject to change without notice. Please refer to www.littelfuse.com/series/c-iii.html for current information. power dissipation is the energy (watt-seconds) per pulse times the number of pulses per second. The power so developed must be within the specifications shown on the device. The operating values of a MOV need to be derated at high temperatures as shown above. Because varistors only dissipate a relatively small amount of average power they are not suitable for repetitive applications that involve substantial amounts of average power dissipation.
