PRECAUTIONS
• Neither addition nor subtraction of output voltages are possible
by the combination of converter outputs. Please contact TDK to
discuss applications that require such voltage combinations.
• When a fuse is connected to the input to prevent smoke and fire,
etc. damage during abnormal events, this fuse should have a
current rating 3 to 8 times that of the rated(normal) input current.
• Caution is required when combining the converter output with
that of another power source(including the converter input power
source) for the operation of load circuitry. Please contact TDK to
discuss such applications.
• Since the converter is entirely shielded by a metal case, care
should be taken to isolate the case from the surrounding
components and wiring pattern.
• Although no specific cleaning requirements are provided for
post-solder flux cleaning, cleaning verification testing is
recommended if such flux cleaning is required. Please discuss
cleaning with TDK if results from such tests are unclear.
