The following bulleted items are considerations
regarding the external components for the typical
application shown in Fig. 5.
 Input electrolytic capacitor C1. We recommend

1-2 µF/W for 48 V applications, and 2-4 µF/W for
24 V applications. This capacitor is needed to
ensure stability of converters in presence of their
negative input impedance characteristic. Note that
electrolytic capacitors at –40 ºC have 3-5 times
less capacitance than at room temperature, and
therefore it is good practice to check the power
system at worst case conditions from this point of
view, i.e. lowest ambient temperature, minimum
input voltage, and maximum load. If electrolytic
capacitors are restricted for use in the system,
please contact the factory.

Common-mode capacitor (Y-cap) values and
their EMI attenuation effects depend on system
grounding and layout (they are not shown on Fig.
5). In EMI testing with the filter, ceramic
capacitors between input and output of the
converter (C4 – C7) were very helpful. Typical
values for the capacitor between Vin- and Vout-
are 3,300 pF – 5,100 pF, and for the capacitor
between Vin+ and Vout+, 0 to 3,300 pF.
If connection of capacitors between input and
output
restrictions, connect Y-capacitors only from each
input pin to system ground. The value of these
capacitors in this case is “the bigger the better”
(preferably 0.1 µF or larger). Voltage rating of
Y-capacitors depends on the system isolation
and safety requirements.
Output capacitors C8, C9 are optional to reduce
output ripple. Addition of one-two 47 µF ceramic
capacitors,
applications 3.3 V and below, significantly
decreases output ripple from 25-40 mV peak-to-
peak to 5-10 mV. Recommended capacitor for
these

UL testing was performed with a 12 Amps fuse
(R451012 from Littelfuse). Fuses larger than
12 Amps should not be used. Smaller value
fuses can be used as required for protection to a
lower power limit.
