(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), ∆I (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, third character = # of zeros. M = Inductance tolerance +/- 20% -R suffix = RoHS compliant RoHS 2002/95/EC |
