Standard method was used for testing the MOVs per datasheet specifcations which consisted of driving relevant surge current through the part with the generated combination wave. In real world events, actual peak current through the lamp with typical circuit impedance path will likely be lower. Littelfuse has tested the above part selections to a more stringent level as it complies with our internal testing standards.
