Flat Coils - PG0077NL and PG0084NL Series
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, 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, 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 ther-
mocouple on top of the unit under test. Take note that the component’s
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.
6. Core loss approximation is based on published core data:
Core Loss
= K1 * (f)
1.035
* (K2ΔI)
2.263
Where: Core Loss
= in Watts
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. 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.
9. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed
parts are not necessarily RoHS compliant, but are electrically and
mechanically equivalent to NL versions. If a part number does not have the
"NL" suffix, but an RoHS compliant version is required, please contact
Pulse for availability.
