Notes:

1. The temperature of the component (ambient plus temperature rise) muse be within

thestandard operating temperature range.

6. Core Loss approximation is based on published core data:

Core Loss = K1*(f)^1.035*(K2ΔI)^2.263

2. Inductance at Irated is a typical inductance value for the component taken at rated

current.

Where: Core Loss = in Watts

f = switching frequency in kHz

3. The rated current listed is the lower of the saturation current @ 25°C or the heating

current.

K1 & K2 = core loss factors

ΔI = delta I across the component in Ampere

4. The saturation current, I^SAT, 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, 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.

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” suﬃx to the part

number (i.e. PG0077.401NL becomes PG0077.401NLT). Pulse complies to industry

standard tape and reel speciﬁcation EIA481.
