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 compo-
nent 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 compo-
nent inductance drops by 20% (typical) at an ambient tempera-
ture of 25°C. This current is determined by placing the compo-
nent 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 cur-
rent is determined by mounting the component on a typical PCB
and applying current for 30 minutes. The temperature is mea-
sured 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 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
ΔΔI= delta I across the component in Ampere
K2ΔΔI= 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. PG0377.401 becomes
PG0377.401T). Pulse complies to industry standard tape and reel
specification EIA481.
9. RoHS compliant parts are available. Order RoHS compliant
parts by adding the suffix "NL" to the part number (i.e.
PG0377.401
becomes
PG0377.401
NL and
PG0377.401
T
becomes
PG0377.401
NLT).
10.
The capacitance of the inductor is a typical value measured
at 100kHz, 0.1Vrms using the HP Impedance Analyzer 4192A
between the inductor terminals and the exposed portion of
the E-core (Fig.1).
11.
DIELECTRIC WITHSTAND VOLTAGE: 150VDC between the
inductor terminals and the exposed portion of the E-core (Fig.1).
12.
INSULATION RESISTANCE: 500kΩ MIN, when measured from
the inductor terminals to the exposed portion of the
E-core (Fig.1).
