N
otes: (1) Open Circuit Inductance Test Parameters: 100 kHz, .250 Vrms, 0.0 Adc.
(2) R
MS 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.
(
4) DCR limits +20 °C.
(5) Applied volt-time product (V-us) across the inductor. This value
represents the applied v-us at 300 kHz necessary to generate a core
loss equal to 10% of the total losses for a 40 °C temperature rise.
