(1) The first three digits in the part number signify the size of the
package. The next four digits specify the A
L
, or nanoHenries per turn
squared.
(2) L = Nominal Inductance of a single winding.
(3) I is the lessor of I
( )
and I
( )
.
(4) Peak current that will result in 30% saturation of the core. This
current value assumes that equal current flows in all six windings.
For applications in which all windings are not simultaneously driven
(i.e. flyback, SEPIC, Cuk, etc.), the saturation current per winding
may be calculated as follows:

For multiple windings, the energy capability varies as the square of
the number of windings. For example, six windings (either parallel
or series) can store 36 times more energy than one winding.
(9) Thermal Resistance is the approximate surface temperature rise
per Watt of heat loss under still-air conditions. Heat loss is a
combination of core loss and wire loss. The number assumes the
underlying PCB copper area equals 150% of the component area.
(10) These devices are designed for feed-forward applications, where
load current dominates magnitizing current.
Number of Windings Driven
(5) RMS Current that results in a surface temperature of approximately
40°C above ambient. The 40°C rise occurs when the specified
current flows through each of the six windings.
(6) Maximum DC Resistance of each winding.
(7) For multiple windings in series, the volt-µsecond (µVs)
capability varies as the number of windings in series (S):

For multiple windings in parallel, the volt-µsecond

temperature rise depends on total power losses and
size. Any other
PCM
configurations other than those suggested
could run hotter than acceptable.
Certain topologies or applications must be analyzed for needed
requirements and matched with the best
VERSA-PAC
size and
configuration. Proper consideration must be used with all
parameters, especially those associated with current rating, energy
storage, or maximum volt-seconds.
VERSA-PAC
should not be used in off-line or safety related
applications. The breakdown voltage from one winding to any other
winding is 500 VAC maximum.
