1. Actual temperature of the component during system operation (ambi-
ent plus temperature rise) must be within the standard
operating range.
2. Inductance at Irated is a typical inductance value for the
component taken at rated current.
3. The rated current as listed is either the saturation current (@ 25°C) or
the heating current depending on which value is lower.
4. The DCR of the part is measured at an ambient temperature of 20°C
±3°C from point a and b as shown above on the mechanical drawing.
5. 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 compo-
nent in the specified ambient environment and applying a short dura-
tion pulse current (to eliminate self-heating effect) to the component.
6. The heating current, Idc, is the DC current required to raise the compo-
nent 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
components' performance 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.
7. Core loss approximation is based on published core data:
Core Loss
= K1 * (f)
1.48
* (K2ΔI)
1.97
Where: Core Loss
= in Watts
K1=
5.894E-10
f
= switching frequency in kHz
K1 & K2
= core loss factors
Δ
I
= delta I across the component in Ampere
Δ
K2*ΔI
= one half of the peak to peak flux density
across the component in Gauss
8. Unless otherwise specified, all testing is made at
100kHz, 0.1V
AC
.
9. Optional Tape & Reel packaging can be ordered by adding a “T”
suffix to the part number (i.e. PG0642.222NL becomes
PG0642.222NLT). Pulse complies to industry standard tape and reel
specification EIA481. The tape and reel for this product has a width
(W=24mm), pitch (Po=12mm) and depth (Ko=5.5mm).
