: DC current for an approximate temperature rise 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. I
sat
1: Peak current for approximately 30% rolloff at +25 °C.
4. I
sat
2: Peak current for approximately 40% rolloff at +125 °C.
5. K-factor: Used to determine Bp-p for core loss (see graph). B
p-p
= K * L *
∆I.
B
p-p
:(Gauss), K: (K-factor from table), L: (Inductance in µH),
∆I
(peak-to-peak ripple
current in amps).
6. Part Number Definition: DRAxxx-yyy-R
•
DRAxxx = Product code and size
•
yyy= Inductance value in µH, R = decimal point,
if no R is present then third character = number of zeros.
•
-R suffix = RoHS compliant
