1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.1Vrms, 0.0Adc, @ +25°C

represent absolute maximum ratings. 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.

K: (K-factor from table), L: (Inductance in nH), ΔI (Peak to peak ripple current in Amps).

8. Part Number Definition: FP1108Lx-Rxxx-R

FP1108L = Product code and size

x= Version indicator

Rxxx= inductance value in μH, R= decimal point ,

-R suffix = RoHS compliant

Dimensions (mm)

Part marking: 1108Lx (x = Version indicator), Rxxx = Inductance value in uH (R= decimal point)

wwllyy = date code, R = revision level

All soldering surfaces to be coplanar within 0.1 millimeters

PCB tolerances are ±0.1 millimeters unless otherwise specified

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

Do not route traces or vias underneath the inductor
