(1) Test Parameters: 100kHz,.0.25 Vrms 0.0Adc
(2) Irms: DC current for approximately ΔT of 40°C without core loss. It is recommended that the
temperature of the part not to exceed 125°C. Derating is necessary for AC currents
(3) Isat: Peak current for approximately 30% rolloff @20°C
(4) DCR limits @20°C
(5) Applied Volt-Time product (V-µS) across the inductor at 100kHz necessary to generate a core loss equal
to 10% of the total losses for a 40°C temperature rise. Derating of the Irms is required to
prevent excessive temperature rise.
Part Number Definition:
