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).

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! 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 lower rated output power (IF_S(D)-W25 Series). 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.
