It should also be noted that the inductance and the frequency of
the “LC“ filtering network should be staggered with the DC/DC
frequency to avoid mutual interference. However, the capacitance of
the output filter capacitor must be proper. If the capacitance is
too big, a startup problem might arise. For every channel of output,
provided the safe and reliable operation is ensured, the greatest
capacitance of its filter capacitor sees (Table 1).
*Test ripple and noise by "parallel cable"method. See detailed operation instructions at Testing of
Power Converter section, application notes.
Note: Dual output models unbalanced load: ±5%

It's not recommend to connect any external capacitor in the application field
with less than 0.5 watt output.
Output Voltage Regulation and Over-voltage Protection Circuit
The simplest device for output voltage regulation, over-voltage and
over-current protection is a linear voltage regulator with overheat protection
that is connected to the input or output end in series (Figure 2).
OUTLINE DIMENSIONS & PIN CONNECTIONS
Overload Protection
Under normal operating conditions, the output circuit of these
products has no protection against overload. The simplest method is
to connect a self-recovery fuse in series at the input end or add a circuit
breaker to the circuit.
No parallel connection or plug and play.
Note:
1. All specifications measured at Ta=25℃, humidity<75%,nominal input
voltage and rated output load unless otherwise specified.
2. Only typical models listed, other models may be different,
please contact our technical person for more details.
3. Operation under minimum load will not damage the
converter; However, they may not meet all specification listed.
RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°C for 10 seconds.
The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin
with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this
series are backward compatible with Sn/Pb soldering systems.
