High potential test voltage:
Temperature range (operation and storage):
Design corresponding to:
Flammability corresponding to:
MTBF @ 40°C/75V (Mil-HB-217F):
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 require-
ments 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.
