- Product marking: ## ~~**Current Energy and Power Dissipation Ratings**~~ Should transients occur in rapid succession, the average 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 Ratings and Specifications Table for the specific 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. ## **Figure 1A - Power Derating for Epoxy Coated** **==> picture [193 x 133] intentionally omitted <==** **----- Start of picture text -----**

NOTE: If pulse ratings are exceeded, a shift of VN(DC)(at specified current) of more then +/-10% could result.
