(1) Open Circuit Inductance Test Parameters: 100 kHz, 0.1 V, 0.0 Adc.

(3) Isat Amperes peak for approximately 30% rolloff (@+20 °C)

(4) K-factor: Used to determine B p-p for core loss (see graph).

B p-p = K*L*∆I, B p-p(mT), K: (K factor from table), L: (Inductance in uH),

∆(Peak to peak ripple current in Amps).

(2) Irms: DC current for an approximate DT of 40 °C 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.

Dimensions- mm

Dimensions are in millimeters.

Part Marking:

3 Digit Marking: (1st digit: Indicates inductance value per letter in Part Marking Designator); (2nd digit: Bi-weekly production date code); (3rd digit: Last digit of the year produced).

Do not route traces or vias underneath the inductor

Packaging information- mm

Parts packaged on 13" Diameter reel,

4,100 parts per reel.
