Abstract

Defines 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.
