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
component temperature by approximately 40°C. The heating
current is determined by mounting the component on a typical
PCB and applying current for 30 minutes. The temperature is
measured by placing the thermocouple on top of the unit under
test. Take note that the component’s performance varies depend-
ing 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)
1.30
* (K2ΔI)
2.41
Where: Core Loss
= in Watts
K1
= 1.20E-10
f
= switching frequency in kHz
K1 & K2
= core loss factors
Δ
I
= delta I across the component in Ampere
Δ
K2ΔI
= 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: PG0155.331NLT).
