Notes:

1. Actual 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

depending on which value is lower.

4. The DCR of the part is measured at an ambient temperature of 20C 3C from point a and b as

shown above on the mechanical drawing.

(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.

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.

7. Core Loss approximation is based on published core data:

Core Loss = K1 * (f) * (K2

ΔI)

Where: Core Loss = in Watts

K1 = 2.20E-11

f = switching frequency in kHz

K1 & K2 = core loss factors

ΔI = delta I across the component in Ampere

K2*

ΔI = one half of the peak to peak flux density

across the component in Gauss

9. Optional Tape & Reel packaging can be ordered by adding a “

T” suffix to the part

number (i.e. PG0702.401NL becomes PG0702.401NL

T). Pulse complies to industry

standard tape and reel specification EIA481. The tape and reel for this product has

a width (W=24.0mm), pitch (Po=16mm) and depth (Ko=8.9mm).
