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.

5 Part Number Definition: MPIA4040RX-XXX-R

• MPIA4040X = 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.
