Notes from Tables
1. The temperature of the component (ambient plus temperature rise) must be within
the specified operating temperature range.
2. The saturation current, I
SAT
, 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, 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 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) * (K2ΔI)
Where: Core Loss
= in Watts
f
= switching frequency in kHz
K1 & K2
= core loss factors
ΔI
= delta I across the component in Ampere
K2ΔI
= one half of the peak to peak flux density
across the component in Gauss
5. Unless otherwise specified, all testing is made at 100kHz, 0.1V
AC
.
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.
