These off-the shelf parts can be used
to create thousands of configurations,
providing a convenient method for
designers to create custom magnetics.
By connecting the windings in series
or parallel, the Hexa-Path compo-
nents can be configured as inductors,
coupled inductors and transformers for
use in virtually any application:flyback,
buck/boost, push-pull, forward, full and
half bridge, Cuk, and SEPIC.
One 6-filar winding
Two trifilar windings
Three bifilar windings
There are six different sizes available
with five HP parts and five HPH parts
in each size.The HP offers lower DCR
and higher Irms ratings. The HPH
offers higher inductance and greater
energy storage capabilities.

2. Inductance is per winding, measured at 100 kHz,
0.1 Vrms, 0 Adc.
3. DCR is per winding, measured on Cambridge
Technology micro-ohmmeter or equivalent.
4. Volt-time product is for a single winding or multiple
windings connected in parallel.To calculate volt-
time product for windings connected in series, mul-
tiply the value specified in the table by the number
of windings connected in series.
5. Peak energy storage is for any combination of wind-
ings, assuming saturation current applied. See note
6 for definition of saturation current.

6. DC current at which the inductance drops 30ꢀ typ
from its value without current, based on current
applied to all six windings connected in series. For
applications where all windings are not connected
in series, use the following equation to calculate
Isat:

Isat = Isattable × 6 ÷ number of windings in series.
7. Current that causes a 40°C rise from 25°C ambient
due to self heating, tested with continuous current
flow through all windings connected in series.
Application temperature rise will depend on the op-
erating current, duty cycle, and winding connection.
8. Part is designed exclusively for use as a forward
converter transformer and was not tested for energy
storage and saturation current.

Connecting windings in series
For higher inductance, the windings can be connected in series. As inductance
increases, energy storage and Irms remain the same, but DCR increases and
Isat decreases.

Isat = 0.975 A
Irms = 1.73 A
Irms = Irmstable = 1.73 A

Connecting windings in parallel
To increase current ratings, the windings (Wn) can be connected in parallel. DCR
decreases, current ratings increase, and inductance remains the same.
