(1) Open Circuit Inductance Test Parameters: 100kHz, 1.0V, 0.0Adc.
(2) Irms: DC current for an approximate
T 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.
(3) Isat Amperes peak for 20% maximum 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 H),
I (Peak to peak ripple current in Amps).
(5) Part Number Definition: FP1308-xxx-R
FP1308 = Product code and size; -xxx = Inductance value in uH;
R = decimal point; If no R is present, third character = # of zeros.
-R suffix = RoHS compliant
RoHS
2002/95/EC
Dimensions are in millimeters.
wwlly = Date Code. R = Revision level.
