1) Units supplied in Tape & Reel packaging;900 parts on 13" diameter reel.
2) OCL (Open Circuit Inductance) Test parameters: 1MHz, .100Vrms, 0.0Adc & ISAT @20°C
3) Applied Volt-Time product (V-µS) across the inductor. This value represents the applied V-µS at 500kHz necessary to generate a core loss equal to 10% of the total losses for 40°C temperature rise.
4) DC current for an approximate ∆T of 40°C without core loss. Derating is necessary for AC currents. PCB layout, trace thickness and width, airflow, and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 155°C under worst case operating conditions verified in the end application.
5) Peak Current for approximately 30% rolloff @ 20°C
