1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.10Vrms, 0.0Adc
2. Irms: 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.
3. Isat: Peak current for approximately 30% rolloff at +25°C.
4. K-factor: Used to determine Bp-pfor core loss (see graph).
Bp-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
• MPI4040R = product code and size
• X = version indicator
• XXX = inductance value in μH, R= decimal point - If no R is present, then last character 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.
