IEC Inlet Filters FN 9246
High Performance IEC Inlet Filter
Rated currents up to 20 A
Approvals
Optional medical versions (B type)
Rear mounting
Excellant attenuation in the lower
frequency range
The FN 9246 IEC inlet filter combines an IEC inlet and
mains filter with excellent filter attenuation in a small
form factor. Choosing the FN 9246 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 current ratings and low
leakage versions for medical applications are
designed to offer you the desired solution.
