SMT Power Inductors

Flat Coils - PG0255NL Series

SPM2007 (07/14)

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 inductance at Bias is the controlled inductance value measured after subjecting

the part to the listed dc bias current.

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.

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

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. PG0255.601NL becomes PG0255.601NL

T). Pulse complies to industry

standard tape and reel specification EIA481.
