VERSA-PAC® Inductors and Transformers (Surface Mount)
Technical Data 4301
Effective August 2017
(1) The first three or four digits in the part number signify the size of the
package. The next four digits specify the AL, or nanoHenries per turn
squared. -R indicates RoHS compliant.
(2) LBASE = Nominal Inductance of a single winding.
(3) IBASE is the lessor of ISAT(BASE) and IRMS(BASE).
(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:
ISAT=6 x ISAT(BASE)
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-µsecondTOTAL (µVs) capability
varies as the number of windings in series (S):
Volt-µsecTOTAL = S xVolt-µsec(BASE)
For multiple windings in parallel, the volt-µsecondTOTAL (µVs) capability
is as shown in the table above.
(8) Maximum Energy capability of each winding. This is based on 30%
saturation of the core:
EnergySERIES = S2
x1x0.7LBASE xI2
SAT(BASE)
2
EnergyPARALLEL = P2
x1x0.7LBASE xI2
SAT(BASE)
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.
2
VERSA-PAC 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.

Where:
LBASE = Inductance of a single winding

Windings on the same magnetic core behave differently. Two windings in series result in four times the inductance of a
single winding. This is because the inductance varies proportionately to the square of the turns.
Paralleled VERSA-PAC windings result in no change to the net inductance because the total number of turns remains
unchanged; only the effective wire size becomes larger. Two parallel windings result in approximately twice the current
carrying capability of a single winding. The net inductance of a given PCM configuration is based on the number of
windings in series squared multiplied by the inductance of a single winding (LBASE). The current rating of a PCM configuration
is derived by multiplying the maximum current rating of one winding (IBASE)by the number of windings in parallel. Examples
of simple two-winding devices are shown below:
Discrete inductors combine like resistors, when connected in series or parallel. For example, inductors in series add and
inductors in parallel reduce in a way similar to Ohm’s Law.
LSeries = L1 + L2 + L3...Ln
LParallel =1/ [1/L1 + 1/L2 + 1/L3....1/Ln]

PIN CONFIGURATIONS
(2,12)(3,11)(4,10)(5,9)(6,8)
Each VERSA-PAC can be configured in a variety of ways by simply connecting pins together on the Printed Circuit Board
(PCB). As shown below, the connections on the PCB are equal to the pin configuration statement shown at the bottom of the
schematic symbol. Connecting a number of windings in parallel will increase the current carrying capability, while connecting
in series will multiply the inductance. Each VERSA-PAC part can be configured in at least 6 combinations for inductor use or
configured in at least 15 turns ratios for transformer applications. The VERSA-PAC allows for at least 500 magnetic
configurations. The PCM configurations can either be created by the designer or simply chosen from the existing PCM
diagrams. The following inductor example shows 6 windings in series, which result in an inductance of 36 times the base
inductance and 1 times the base current.
INDUCTOR EXAMPLE
FOR SIZES VP3, VP4 AND VP5
The PCM configurations may be selected from the examples above or created by the designer. The printed circuit board
layout in each example illustrates the connections to obtain the desired inductance or turns ratio. The examples may be
used by the PCB designer to configure VERSA-PAC as desired.
To assist the designer, VERSA-PAC phasing, coupling and thermal issues have been considered in each of the PCM
configurations illustrated. Additionally, the inductance and current ratings, as a function of the respective base values are
shown in each PCM example.
It is important to carefully select the proper VERSA-PAC part in order to minimize the component size without exceeding
the RMS current capability or saturating the core. The Product specification table indicates maximum ratings.
Each VERSA-PAC may be used in at least 15 transformer applications. More than 375 transformer combinations may be
achieved using the available VERSA-PAC parts.

VERSA-PAC® Inductors and Transformers (Surface Mount)
5V to 3.3V Buck Converter With 5V Output
This circuit minimizes both board space and cost by eliminating a
second regulator.VERSA-PACsgap serves to prevent core
saturation during the switch on-time and also stores energy for the
+5V load which is delivered during the flybackinterval. The +3.3V
buck winding is configured by placing two windings in series while
the +5V is generated by an additional flyback winding stacked on
the 3.3V output. Extra windings are paralleled with primary
windings to handle more current. The turns ratio of 2:1 adds 1.67V
to the +3.3V during the flyback interval to achieve +5V.

3.3V Buck Converter
This circuit utilizes the gap of the VP5-0083 to handle the 12.5
Amp output current without saturating. In each of the five VERSA-
PAC sizes, the gap is varied to achieve a selection of specific
inductance and current values (see VERSA-PAC Data Table).
All six windings are connected in parallel to minimizeAC/DC
copper losses and to maximize heat dissipation. With VERSA-
PAC, this circuit works well at or above 300 KHz. Also, the closed
flux-path EFD geometryenables much lower radiation
characteristics than open-path bobbin core style components.
LITHIUM-ION BATTERY TO 3.3V SEPIC CONVERTER
The voltage of a Lithium-Ion Battery varies above and below
+3.3V depending on the degree of charge. The SEPIC
configuration takes advantage of VERSA-PAC’s multiple tightly
coupled windings. This results in lower ripple current which lowers
noise and core losses substantially. The circuit does not require a
snubber to control the voltage “spike” associated with switch turn-
off,and is quite efficient due to lower RMS current in the windings.
