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.

To ensure this module can operate efficiently and reliably, During operation, the minimum output load could not be less than 10% of the full 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 

products with a lower rated output power (D-NXT-2W).

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.

If you want to further decrease the input/output

ripple , a capacitor

filtering network may be connected to the input and output ends of

the DC/DC

converter, see (Figure 2).

It should also be noted

that the capacitance of

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 recommended capacitance of its filter capacitor sees (Table 1).

It's not recommended to connect any external capacitor in the application field with less than 0.5 watt output.

The simplest device for output voltage regulation, over-voltage and over-current protection is a linear regulator and an capacitor

filtering network with

overheat protection that is connected to the input or output end in series (Figure 3),
