1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.25V , 0.0Adc @ 25°C.
2. Full Load Inductance (FLL) Test Parameters: 100kHz, 0.25V , I @ 25°C.

3. I : DC current for an approximate temperature rise of 40°C without core loss. Derating is
rms
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°C under worst case operating conditions verified in the
end application.
4. I : Peak current for approximately 20% rolloff at +25°C.
