E-XSR Series
Filtering
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).
In some circuits which are sensitive to noise and ripple.a
filtering capacitor may be added to the DC/DC output
end and input 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).

It's not recommend to connect any external capacitor in
the application field with less than 0.5 watt output.
Overload Protection
Under normal operating conditions, the output circuit
of these products has no protection against over-current
and short-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
To ensure 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!
When the environment temperature is higher than
71℃, the product output power should be less then
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.
