Scope
This standard covers test methods and performance values for metal-oxide varistor (MOV) surge protective components (SPCs) with the following main parameter ranges: ?? Packaging: Leaded disc-type or surface mount ?? Nominal varistor voltage: 5 V to 1200 V ?? 8/20 surge current rating: 10 A to 70 kA ?? 8/20 clamping voltage: 10 V to 3 kV With appropriate component selection@ these components could be used for the overvoltage protection of power and signal systems having the following: ?? Continuous ac voltages: 2.5 V rms to 750 V rms ?? Steady-state dc voltages: 3.3 V to 1000 V ?? Peak signal feed voltages: 3.5 V to 850 V Information is given on manufacturer type testing used to determine environmental performance and rated values.
