notes from tables
Round Wire Coils - PG0702NL Series
1.
Actual temperature of the component during system opera -
tion (ambient 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 component
in the specified ambient environment and applying a short duration pulse
current (to eliminate self-heating effect) to the component.
6. The heating current, Idc, 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 typi-
cal pcb and applying current for 30 minutes. The temperature is
measured by placing the thermocouple in the coil 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)
1.12
* (K2DI)
2.17
Where: Core Loss
= in Watts
K1=
2.20E-11
f
= switching frequency in kHz
K1 & K2
= core loss factors
DI
= delta I across the component in Ampere
K2DI
= one half of the peak to peak flux density
across the component in Gauss
Unless otherwise specified, all testing is
100kHz, 0.1V
AC

Optional Tape & Reel packaging can be ordered by adding a “T” suffix to
the part number (i.e. PG0702.401NL becomes PG0702.401NLT). Pulse
complies to industry standard tape and reel specification EIA481. The
tape and reel for this product has a width(W=24.0mm), pitch(Po=16.0mm)
and depth (Ko=8.9 mm).
