1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.10V

2. I

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. I

rms

testing was performed on a 19.05mm long x 6.35mm wide x 0.070mm thick copper trace in still air.

4. K-factor: Used to determine B

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.
