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-p for core loss (see graph). Bp-p = K * L *
ΔI.
Bp-p : (Gauss), K:
(K-factor from table), L: (inductance in
μH), ΔI
(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.
