DATASHEET
PCB Filters FN 409
75 VDC Input PCB Filter
Rated currents from 3 to 13 A, 75 VDC
Very compact PCB-mounting design
Approvals
Exceptional attenuation performance
High frequency noise compression
FN 409 PCB filters are designed to surpress common
and differential-mode noise on DC voltage lines. The
suppression performance is special designed to fulfill
the requirements for high frequency switching
DC/DC converter modules. FN 409 filters can also be
used to filter the output current of switch-mode
power supplies in applications with intelligent power
distribution.
