1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.1Vrms, 0.0Adc@25°C

2. Full Load Inductance (FLL) Test Parameters: 100kHz, 0.1Vrms, Isat1

3. Irms: DC current for an approximate temperature rise of 40°C without core loss. Derating is

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. Isat1: Peak current for approximately 20% rolloff @ 25°C

5. Isat2: Peak current for approximately 20% rolloff @ 85°C

6. Isat3: Peak current for approximately 20% rolloff @ 125°C

7. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L

* ∆I * 10-3. Bp-p:(Gauss), K: (K-factor from table), L: (Inductance in nH),

∆I (Peak to peak ripple current in Amps).
