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 ΔT of 40°C without core loss. Derating is neces-
sary for AC currents. PCB layout, trace thickness and width, airflow, and proximi-
ty of other heat generating components will affect the temperature rise. It is rec-
ommended 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
