Packaging information - mm

Dimensions- mm

2 Full Load Inductance (FLL) Test Parameters: 100kHz, 0.1Vrms, Isat1

3 Irms: DC current for an approximate temperature rise of 40°C without core loss. Derating is

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

generating components will affect the temperature rise. It is recommended the part temperature not exceed

125°C under worst case operating conditions verified in the end application.

4 Isat1: Peak current for approximately 20% rolloff at +25°C. 5 Isat2:

5 Peak current for approximately 20% rolloff at +125°C.

6 K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ΔI * 10

-3, B

p-p : (Gauss),

K: (K-factor from table), L: (inductance in nH),

ΔI (peak-to-peak ripple current in amps).

• Rx is the DCR indicator

• FP1107 = Product code and size

• Rxx= Inductance value in

μH, R = decimal point

• “-R” suffix = RoHS compliant
