F & FC Series DC-DC Converter Input Filters
F4804A, 0-80V, 4 Amps, SMT Mount
The F4804A filter contains input and output
capacitors, plus differential and common mode
inductors. The separate differential inductor, L2,
allows a differential attenuation of 55 dB, a value
substantially higher in comparison with other
available off-the-shelf filters (typically 25-30 dB).
Absolute maximum voltage and maximum operating
voltage in Electrical Specifications Table are for the
filter itself; check maximum rating for corresponding
dc-dc converters. Filter will not be damaged by
reversed input voltage, or by applying voltage to the
output pins.

Fig. 1: Schematic diagram.
Differential attenuation plot in the frequency range of
50 kHz-100 MHz is shown in Fig. 2, and can be seen
to be flat (around 55-60 dB) from 0.5 MHz to
50 MHz.
Fig. 2: Differential mode attenuation, 0.05-100 MHz. Source
and load resistances are 50 . Vertical scale: 20 dB/div, with
zero level marked by arrow. No load @ 25 C.
Fig. 3 and Fig. 4 show Common mode attenuation with
50 source and load. The attenuation depends on the
value of external Y-capacitors, connected between input
pins and frame or a reference ground.
Fig. 3: Common Mode attenuation, 0.05-100 MHz. Source and
load resistances are 50 . Two 0.1 F Y-caps to common
line. Vertical scale: 20 dB/div, with zero dB level marked by
arrow.
Fig. 4: Common Mode attenuation, 0.05-100 MHz. Source and
load resistances are 50 . Two 0.47 F Y-caps to common
line. Vertical scale: 20 dB/div, with zero dB level marked by
arrow.
