The FN 9233 IEC inlet filter combines an excellent IEC
inlet and mains filter with excellent filter attenuation
in a small form factor. Choosing the FN 9233 product
line brings you the rapid availability of a standard
filter associated with the necessary safety
acceptances. Standard IEC connector filters are a
practical solution helping you to pass EMI system
approval in a short time. A wide selection on
amperage ratings, output connections, mounting
possibilities and filters for medical applications are
designed to offer you the desired solution. For types
with additional earth line choke please consult the FN
9233E data sheet.
