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

(2) Irms: DC current for an approximate ∆T of 30 °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.

(3) Isat Amperes peak for approximately 15% rolloff (@+25 °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 µH),

∆(Peak to peak ripple current in Amps).

(5) Part Number Definition: LDS0705-xxx-R

LDS0705 = Product code and size; -xxx = Inductance value in uH;

R = decimal point; If no R is present,

last character equals number of zeros.

M = Inductance tolerance +/- 20%

-R suffix = RoHS compliant

Marking: xxx = Inductance in uH. R = decimal point. If no R is present last character

equals number of zeros. wwllyy = Date code, R = Revision level.

Do not route traces or vias underneath the inductor
