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).

OUTLINE DIMENSIONS & PIN CONNECTIONS IF IF--XS-1W SIP SIZE Graph Overload Protection IF IF--XD-1W DIP 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).
