Abstract

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.
