(1) Open Circuit Inductance test parameters: 100kHz, 0.25V, 0.0Adc,
tolerance is ±20%
(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 165°C under worst
case operating conditions verified in the end application.
(3) Isat Amperes peak for approximately 30% rolloff (@25°C)
(4) Isat Amperes peak for approximately 40% rolloff (@125°C)
(5) DCR limits @ 25°C
(6) 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).
(7) Part Number Definition: DRAxxx-xxx-R
DRAxxx = 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
[Increase knowledge] Tips to prevent PCB board warping after design
One of the causes of warping of printed circuit boards is that the substrate (copper clad laminate) used may warp. However, during the processing of printed circuit boards, thermal stress, chemical fa...
