rms
: DC current for an approximate temperature rise of 40°C without core
loss. De-rating is necessary for AC currents. Temperature rise is dependent
upon several factors, including the PCB pad layout, trace thickness and width,
air-flow and proximity to other heat generating components. It is
recommended the part temperature not exceed 125°C under worst case
operating conditions and therefore, the temperature rise should be verified
in the end use application. Irms testing was performed on a 19.05mm long x
6.35mm wide x 0.070mm thick copper trace in still air.

sat
: Peak current for approximately 30% rolloff at +25°C.
4 K-factor: Used to determine B
p-p
for core loss (see graph). B
p-p
= K * L * DI.
Bp-p : (Gauss), K: (K-factor from table), L: (inductance in µH),
DI (peak-to-peak ripple current in amps).
5 Part Number Definition: MPI4040RX-XXX-R
• MPI4040X = product code and size
• XXX = inductance value in all, “R” = decimal point
- If no “R” is present, then third digit equals the number of zeros
• “-R” suffix = RoHS compliant
† Transient pulse not to exceed 1 millisecond.
†† Maximum operating frequency less than 10MHz, consult factory for
application specific values.
