SMT POWER INDUCTORS
Flat Coils - PG0077 and PG0084 Series
Notes from Tables
1. The temperature of the component (ambient plus temperature rise) must
be within the standard operating temperature range.
2. Inductance at Irated is a typical inductance value for the component taken
at rated current.
3. The rated current listed is the lower of the saturation current @ 25°C or
the heating current.
4. The saturation current, Isat, is the current at which the component
inductance drops by 20% (typical) at an ambient temperature of 25°C.
This current is determined by placing the component in the specified
ambient environment and applying a short duration pulse current (to
eliminate self-heating effects) to the component.
5. The heating current, I
DC
, is the DC current required to raise the compo-
nent temperature by approximately 40°C. The heating current is deter-
mined by mounting the component on a typical PCB and applying current
for 30 minutes. The temperature is measured by placing the thermocou-
ple on top of the unit under test. Take note that the component’s perfor-
mance varies depending on the system condition. It is suggested that the
component be tested at the system level, to verify the temperature rise of
the component during system operation.
6. Core loss approximation is based on published core data:
Core Loss
= K1 * (f)
0.5539
* (K2∆I)
2.2355
Where: Core Loss
= in Watts
f
= switching frequency in kHz
K1 & K2
= core loss factors
∆
I
= delta I across the component in Ampere
∆
K2∆I
= one half of the peak to peak flux density
across the component in Gauss
7. Unless otherwise specified, all testing is made at 100kHz, 0.1V
AC
.
8. Add suffix
"T"
to the part number for Tape & Reel packaging
(ex: PG0077.181T).
