Notes: (1) Open Circuit Inductance Test Parameters: 100KHz, .250Vrms, 0.0Adc. (2) RMS current for an approximate T of 40C without core loss, at an ambient temperature of 85C. (3) Peak current for approximately 30% rolloff @ 20C.
(4) DCR limits 20C. (5) Applied volt-time product (V-uS) across the inductor. This value represents the applied v-us at 300KHz necessary to generate a core loss equal to 10% of the total losses for a 40 temperature rise.
