PH
C2, C3: 4700pF
Use a ceramic capacitor that has high withstand voltage to
reduce the output spike voltage.
Select the capacitor from the above recommended compo-
nents with high withstand voltage because the test voltage
is applied to the capacitor during the withstand voltage
test in some application contents.
Connect C2 between +Vin and baseplate and C3 between
-Vin and baseplate as short as possible.
C4: 2.2μF
Also, use a ceramic capacitor to reduce the output noise
voltage.
Attach the ceramic capacitor between +V and -V where
less than 50mm from output terminal for PH300S.
For PH600S, attach the ceramic capacitor between +V
and -V terminal as short as possible.
The output spike noise voltage could be changed for de-
sign of printed circuit board.
C5:
Use electrolytic capacitor(s) for stable operation.
Attach the electrolytic capacitor between +V and -V where
less than 50mm from output terminal for PH300S.
For PH600S, attach the electrolytic capacitor between +V
and -V terminals as short as possible. Recommend tighten
the screws of load wire and C5 together.
Oscillation waveform could be shown at dropping down the
output for characteristics of equivalent series resistance
(ESR) of electrolytic capacitor and equivalent series induc-
tance (ESL).
Moreover, note the output ripple voltage could be changed
for design of printed circuit board.
In case input/output dynamically changes, it helps the fluc-
tuation of output voltage by increasing the external capaci-
tor value.

C6:
In between input source and input line of PH300S, 600S
series there are a switch and connectors etc. In case that
the switch is on/off or plug in/off when the input is apply-
ing, attach an electrolytic capacitor, C6 as shown as Fig-
ure1-3.
Because in-rush current flows when the input is applied,

Recommended Values
If plural numbers of module will be connected in PH300S,
PH600S series, attach an electrolytic capacitor, C6 as
shown as Figure1-4.

pacitor. Especially be aware it when the load current is in
dynamics.
The output voltage may be greatly varied in 300Hz - 2kHz
frequency range at 0%←→100% of dynamic load condition.
For less dynamic of the voltage, use a electrolytic capacitor
which has better capacity than recommended electrolytic
capacitor or keep the minimum load current more than 10%
of nominal current.
