A method of assembling an electromagnetic interference filter comprises the step of disposing electrical components on a base. The components are connected to form an electromagnetic interference filter. The filter is enclosed in a metal case, which is formed by folding a metal sheet around said filter and joining the ends of the sheet together. The metal sheet has an insulating coating disposed on one side to prevent contact between the filter components and the case. The outer surface of the case is sealed with seal tape.
