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 ºC under worst case operating conditions verified in the end

application.

4.

K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * I. Bp-

p:(Gauss), K: (K-factor from table), L: (Inductance in µH), I (Peak to peak ripple current in

Amps).

Part Number Definition: MPI25xxV1-xxx-R

MPI25 = Product code

xx= Height indicator

V1=Versionl indicator

xxx= inductance value in µH, R= decimal point,

If no R is present then last character equals number of zeros

-R suffix = RoHS compliant
