1. The temperature of the component (ambient plus temperature rise) muse be within
thestandard 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 eects) to the component.
5. The heating current, IDC, is the DC current required to raise the component tempera-
ture 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 depending on the system condition. It is sug-
gested 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)1.33 *(K2ΔI)2.51
Where: Core Loss = in Watts
K1 = 1.05E-10
f = switching frequency in kHz
K1 & K2 = core loss factors
ΔI = delta I across the component in Ampere
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, 0.1VAC.
8. Optional Tape & Reel packaging can be ordered by adding a “T” sux to the part
number (i.e. PG0434.181NL becomes PG000434.181NLT). Pulse complies to industry
standard tape and reel specification EIA481.
