To get an extreme low ripple,an "LC"filtering network
may be connected to the input and output ends of the
DC/DC converter.Which may produce a more significant
filtering effect.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 see (Figure 1).

TYPICAL CHARACTERISTICS
Temperature Derating Graph
In some circuits which are sensitive to noise and
ripple.a filtering capacitor may be added to the DC/DC
output end andinput end to reduce the noise and ripple.
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).

Under normal operating conditions, the output circuit of
these products has no protection against over-current
andshort-circuits.The simplest method is to connect a
self-recovery fuse in series at the input end or add a
circuit breaker to the circuit.
Requirement On Output Load
Toensure this module can operate efficiently and reliably,
a minimum load is specified for this kind of DC/DC
converter in addition to a maximum load (namely full
load).During operation,make sure the specified range
of input voltage is not exceeded,the minimum output
load is not less than 10% of the full load, and that this
product should never be operated under no load! If the
actual output power is very small, please connect a
resistor with proper resistance at the output end in
parallel to increase the load, or use our company°s
products with a lowerrated output power (IF_S(D)-W25
Series).

When the environment temperature is higher than
C, the product output power should be less then
71
71°C,
60% of the rated power.
No parallel connection or plug and play.
Use dual output simultaneously, forbid opening
output pin (0V) to use as single output.
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.
