DESCRIPTION
The F-XM Series is specially designed for
applications where a group of polar power
supplies are isolated from the input power supply
in a distributed power supply system on a circuit
board.
These products apply to:
1) Where the voltage of the input power supply
is fixed (voltage variation ≤10%);
2) Where isolation is necessary between
input and output (isolation voltage ≤3000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are not demanding.
Such as:purely digital circuits,ordinary low
frequency analog circuits,and IGBT power
device driving circuits.

Requirement on output load
To ensure this module can operate efficiently and reliably,
During operation, the minimum output load is not less than
10% of the full load, and that his 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.
Recommended circuit
If you want to further decrease the input/output ripple,
an "LC" filtering network may be connected to the input and
output ends of the DC/DC converter, see (Figure 1).

*Test ripple and noise by "Parallel cable" method. See detailed operation instructions at Testing of Power
Converter section, application notes.
Note:
1. All specifications measured at T A =25 ℃ , humidity<75%, nominal input voltage and rated output load unless
otherwise specified.
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.
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 recommended
capacitance of its filter capacitor sees (Table 1).
2. See below recommended circuits for more details.
TYPICAL CHARACTERISTICS
It not recommended to connect any external capacitor in
the application field with less than 0.5 watt output.
Output Voltage Regulation and Over-voltage Protection
Circuit
The simplest device for output voltage regulation,
over-voltage and over-current protection is a linear voltage
regulator with overheat protection that is connected to the
input or output end in series (Figure 2).
OUTLINE DIMENSIONS & PIN CONNECTIONS
Overload 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.
No parallel connection or plug and play.

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.
REACH COMPLIANT INFORMATION
This series has proven that this product does not contain harmful chemicals, it also has
harmful chemical substances through the registration, inspection and approval.
