* To compile a complete part number, please replace the -.. with the required I/O connection style (e.g. FN 670-1.8-06, FN 670-10-07).
** Maximum leakage under normal operating conditions. Note: if the neutral line is interrupted, worst case leakage could reach twice this level.
Per CISPR 17; A = 50Ω/50Ω sym; B = 50Ω/50Ω asym; C = 0.1Ω/100Ω sym; D = 100Ω/0.1Ω sym
