1-phase filters
FN 680
Two-stage performance EMI filter
Approvalsn Rated currents from 1 to 10A
n Very high differential and common-mode
attenuation
n Good low frequency attenuation
Typical applications
n FN 680 filters are designed for easy and
fast chassis mounting.
n FN 680 filters offer a perfect combination
of performance/size ratio.
n FN 680 two-stage filters provide a very
high differential and common-mode
attenuation performance, based
on chokes with high saturation resistance
and excellent thermal behavior.
n FN 680 two-stage filters are designed for
very high noise suppression and low
frequency attenuation.
n Faston terminal connection with additional
spade solder possibility or wire connection.
n Custom-specific versions on request.

* To compile a complete part number, please replace the -.. with the required I/O connection style (e.g. FN 680-1-06, FN 682-10-07).
** Maximum leakage under normal operating conditions. Note: if the neutral line is interrupted, worst case leakage could reach twice this level.
