Inductance vs Current Characteristics

Notes from Tables

1. The temperature of the component (ambient plus temperature

rise) must be within the specified 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, 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 effects) to

the component.

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.

6. Core loss approximation is based on published core data:

Where: Core Loss = in Watts

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

8. Optional Tape & Reel packaging can be ordered by adding a "T"

suffix to the part number (i.e. PG0083.472 becomes

PG0083.472T). Pulse complies to industry standard tape

and reel specification EIA481.
