SMT POWER INDUCTORS
Flat Coils - PG0426NL Series
Notes from Tables
1. The temperature of the component (ambient plus temperature
rise) must be within the standard operating temperature range.
2. The saturation current, ISAT, is the current at which the component
inductance drops by 30% (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.
3. The heating current, IDC, 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.
4. Core loss approximation is based on published core data:
Core Loss = K1 * (f)1.33 * (K2
ΔI)2.51
Where: Core Loss = in Watts
K1= 8.75E-12
f = switching frequency in kHz
K1 & K2 = core loss factors
ΔΔI = delta I across the component in Ampere
K2
ΔΔI = one half of the peak to peak flux density
across the component in Gauss
5.
Unless otherwise specified, all testing is made at
100kHz, 0.1VAC.
6.
Optional Tape & Reel packaging can be ordered by adding a "T"
suffix to the part number (i.e. PG0426.101NL becomes
PG0426.101NLT). Pulse complies to industry standard tape and
reel specification EIA481.
