Inductors and Transformers
(Surface Mount)
Description
RoHS
2002/95/EC
• Six winding, surface mount devices that
offer more than 500 usable inductor or
transformer configurations
• High power density and low profile
• Low radiated noise and tightly coupled windings
• Power range from 1 Watt – 70 Watts
• Frequency range to over 1MHz
• 500 VAC Isolation
• Ferrite core material
Applications
• Inductors: buck, boost, coupled, choke, filter, resonant,
noise filtering, differential, forward, common mode
• Transformers: flyback, feed forward, push-pull, multiple
output, inverter, step-up, step-down, gate drive, base
drive, wide band, pulse, control, impedance, isolation,
bridging, ringer, converter, auto
Environmental Data
• Storage temperature range: -55°C to 125°C
• Operating ambient temperature range: -40°C to +85°C
(range is application specific). The internal “hot spot”
temperature defines the maximum allowable currents,
which are limited to 130°C, including ambient
• Solder reflow temperature: +260°C max for 10 seconds
max.

(1) The first three digits in the part number signify the size of the
package. The next four digits specify the AL, 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:
SAT BASE
ISAT
2
EnergySERIES = S x
2
RMS BASE
=
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-µsecond (µVs)
capability varies as the number of windings in series (S):
TOTAL
EnergyPARALLEL = P x
1
2
x
2
1
2
0.7LBASE x I SAT(BASE)
2
x
0.7LBASE x I 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.
Volt-µsecTOTAL = S x Volt-µsec(BASE)
For multiple windings in parallel, the volt-µsecond
is as shown in the table above.

(µVs) capability
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.

Inductors and Transformers

HOW TO USE MULTIPLE WINDINGS
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]
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 (L ). The current rating of a PCM configuration
is derived by multiplying the maximum current rating of one winding (I ) by the number of windings in parallel. Examples
of simple two-winding devices are shown below:

HOW TO PIN-CONFIGURE VERSA-PAC
®
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. Given 25 VERSA-PAC part numbers, this 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.

The PCM configurations may be selected from the examples on the following pages or created by the designer. Six PCM
inductor and fifteen PCM transformer configurations and equivalent circuit schematics are shown. 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 from
the following Data Tables, are shown in each PCM example. Turns ratios are also given for each PCM Transformer shown.
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 Data Tables indicate maximum ratings.
