These off-the shelf parts can be used
to create thousands of configura-
tions, providing a convenient method
for designers to create custom mag-
netics. By connecting the windings
in series or parallel, the Hexa-Path
components 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.

There are six different sizes avail-
able 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,
multiply the value specified in the table by the
number of windings connected in series.
5. Peak energy storage is for any combination of
windings, assuming saturation current applied. See
note 6 for definition of saturation current.
6. DC current at which the inductance drops 30% 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
operating current, duty cycle, and winding
connection.

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.

Example: Calculate new electricals for HP3-0138L with four windings (Wn)
connected in series:
2
Inductance = Inductancetable × Wn
10
6
= 11.2 × 42 = 179.2 µH
DCR = DCRtable × Wn
= 0.055 × 4 = 0.22 Ohms
7
Isat = (Isattable) × 6 ÷ Wn
= (0.65 × 6) ÷ 4 = 0.975 A
L = 179.2 µH
DCR = 0.22 ⏲
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.

Example: Calculate new electricals for HP5-0083L, with three (Wn) windings
connected in parallel (equivalent to one winding in series):
Inductance = Inductancetable

10
11
12

6
DCR = 1 ÷ [Wn × (1 ÷ DCRtable)]
= 1 ÷ [3 × (1 ÷ 0.045)] = 0.015 Ohms
7
Isat = (Isattable × 6) ÷ Wn
= (0.65 × 6) ÷ 1 = 3.9 A
L = 11.2 µH
DCR = 0.015⏲
Isat = 3.9 A
Irms = 5.19 A
Irms = Irmstable × Wn
= 1.73 × 3 = 5.19 A

Connecting secondary windings in parallel
When secondary windings (Wsec) are connected in parallel, DCR de-
creases and Irms increases.
Example: For HPH3-0083L, connect two secondary windings in
parallel:
DCR = 1 ÷ [Wsec × (1 ÷ DCRtable)]
= 1 ÷ [(2 × (1 ÷ 0.125)] = 0.0625 Ohms
Irms = Irmstable × Wsec = 1.13 × 2 = 2.26 A
