1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.1V

rms, 0.0Adc, +25°C

2. Full Load Inductance (FLL) Test Parameters: 100kHz, 0.1V

rms, Isat1, +25°C

3. I

rms: DC current for an approximate temperature rise of 40ºC without core loss. Derating is necessary

for AC currents. PCB layout, trace thickness and width, air-flow, and proximity of other heat generating

components will affect the temperature rise. It is recommended that the temperature of the part

not exceed 125°C under worst case operating conditions verified in the end application.

4. I

sat1: Peak current for approximately 20% rolloff @ +25ºC

5. I

sat2: Peak current for approximately 20% rolloff @ +100ºC

6. I

sat3: Peak current for approximately 20% rolloff @ +125ºC

7. K-factor: Used to determine B

p-p for core loss (see graph).

p-p = K * L * ∆I * 10

-3

. B

p-p:(Gauss), K: (K-factor from table),

L: (Inductance in nH), ∆I (Peak-to-peak ripple current in Amps).

8. Part Number Definition: FP1008Rx-Rxxx-R

FP1008 R= Product code and size

x = DCR indicator

Rxxx = Inductance value in μH, R = decimal point

- R suffix = RoHS compliant

Dimensions (mm)

Part marking: FP1008Rx (x= DCR indicator), Rxxx (xxx=inductance value in uH, R=decimal point),

wwllyy = date code, R = revision level

Tolerances are ±0.15 millimeters unless stated otherwise

PCB tolerances are ±0.1 millimeters unless stated otherwise

All soldering surfaces to be coplanar within 0.1 millimeter

DCR measured from point “a” to point “b”

Do not route traces or vias underneath the inductor
