Thermal Considerations
Because of low series internal DC resistance, the
F4804A filter generally does not require airflow
and/or derating to ambient temperatures up to 85 ˚C,
if placed and interconnected as described below.
Good thermal design includes the appropriate
placement of the filter on the system board as to
maximize heat exchange through the power pins.
For high temperature operation in low airflow
environments, use of 1-2 oz copper for the external
connection pads and provision for some extra copper
at all four I/O pins is encouraged. Good thermal
connection to the power planes is important.

To check filter thermal characteristic in an actual
system environment, attach a thermocouple to the
top of each inductor.
The maximum temperature at these test points
should not exceed 120 ˚C.
A typical application schematic is shown in Fig. 5.
The filter can be used to power one or more
converters.
For applications requiring filter current greater than
4 A divide the converters into smaller groups and
use multiple filters or use a F4810 or F2410 filter
which is capable of providing up to 10 A. Do not
connect filters in parallel.
