Notes: (1) Open Circuit Inductance Test Parameters: 100KHz, .250Vrms, 0.0Adc.
(4) DCR limits 20°C.
(2) RMS current for an approximate ∆T of 40°C without core loss, at an
ambient temperature of 85˚C.
(3) Peak current for approximately 30% rolloff @ 20°C.
(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.
