Thermal Considerations
Because of low series internal DC resistance, the
F4810/F2410 filters generally do not require airflow
and/or derating to ambient temperatures up to 85 ˚C,
if placed and interconnected as described below.
Good thermal design is consistent with appropriate
placement to gain additional heat exchange through
the I/O pins to the system board. 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. Thermal derating data shown
were taken on special thermal board with each input
and output pin connected to 0.5 sq. in pad of 2 oz
copper.
To check filter thermal characteristic in an actual
system environment, attach a thermocouple to the
top of differential inductor, L2; it is the INDUCTOR
closest to OUT+ pin.
The maximum temperature at this test point should
not exceed 120 ˚C, and a minimum of 5-10 ˚C
headroom is suggested for better reliability.

A typical application schematic is shown in Fig. 5.
Either filter can be used to power one or more
converters. Maximum filter output current should be
limited 10 A - or less - depending upon system
thermal environment.

For applications requiring a filter current greater than
10 A, divide the converters into smaller groups and
use multiple filters. Do not connect filters in parallel.
