Fuse interruption characteristics have to be taken into account while designing input traces. User should ensure that Input trace is capable of withstanding fault currents until fuse blows. Note 2: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com) Note 3: For modules with isolation voltage rating of 2250V, order the Feature Set option C. See last page for ordering details. Note 4: Higher values of isolation capacitance can be added external to the module.
