Open Circuit Inductance (OCL) Test Parameters: 1 khz,.1 Vrms,. dc, +5 C. Full Load Inductance (FLL) Test Parameters: 1 khz,.1 Vrms, 1, +5 C. I rms : DC current for an approximate temperature rise of 4 C without core loss. Derating is necessary for C 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 +15 C under worst case operating conditions verified in the end application. 4. 1: Peak current for approximately % rolloff @ +5 C 5. : Peak current for approximately % rolloff @ +1 C 6. : Peak current for approximately % rolloff @ +15 C 7.
