SMT Power Inductors

Round Wires – PG0871NL series

NOTES:

1. Actual temperature of the component during system operation(ambient

plus temperature rise) must be within the standard operating range.

2. Inductance at Irated is a typical inductance value for the component taken

at rated current.

3. The rated current as listed is either 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 20°C±3°C

from point a and b as shown below on the mechanical drawing.

5. The saturation current, Isat, is the current at which the component induc-

tance drop 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 effect) to the component.

6. The heating current, Idc, is the DC current required to raise the com-

ponent 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 ther-

mocouple on top of the unit under test. Take note that the components’

performance varies depending on the system condition. IT is suggested

that the component be tested at the system level, to verify the tempera-

ture rise of the component during system operation.

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

Core Loss = K1 * (f)

* (ΔB)

in mW

K1 = 71.56 E-4

ΔB = K2 * Vusec in mT

f = switching frequency in MHz

K1 & K2 = core loss factors

V = Voltage across the component in V

Vusec = V * D /f

D = Duty cycle

8. Unless otherwise specified, all testing is made at 100kHz, 0.1Vac

9. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to

the part number (i.e. PG0871.222NL becomes PG0871.222NLT). Pulse

complies to industry standard tape and reel specification EIA481. The

tape and reel for this product has a width(W=16.0mm), pitch(Po=12.0mm)

and depth (Ko=6.8 mm).
