Notes:
1. When measuring output ripple & noise, it is recommended
that an external ceramic capacitor (approx
10 µF) be placed from the +VOUT to the -VOUT pins.
2. Transient recovery is measured to within a 1% error
band for a load step change of 25%.
3. Short circuit protection is provided by a “hiccup mode”
circuit.
4, These units should not be operated with a load under 5% of
full load. Operation at no-load will not damage the unit, but
they may not meet all specifications.
5. The recommended reflow settings are a peak temperature
of 245 °C for a maximum period (TPK) of 10S and a time
above liquidous (TL) of <60 seconds at 217 °C. A suggested temperature profile is shown on page four. For more
information, please contact the factory.
6. It is recommended that a fuse be used on the input of a
power supply for protection. See the Model Selection table
above for the correct rating.

Notes:
1. All units are rated for EN 55022 (CE/RE) class A without external components.
They will meet class B with the addition of the MDCFM-0x (or a similar discrete
filter circuit). Contact the factory for more information.
2. To meet the requirements of EN 61000-4-4 (±2 kV or ±4 kV), external components are needed. This can be done discretely, or with the addition of the
MDCFM-0x. Contact the factory for more information.
3. To meet the requirements of EN 61000-4-5 (±2 kV), external components are
needed. This can be done discretely, or with the addition of the MDCFM-0x.
Contact the factory for more information.
