1) OCL (Open Circuit Inductance) Test parameters: 300KHz, .25Vrms,
0.0Adc & Isat.
2) Irms Amperes for approximately
∆T
of 40°C. DC current for an approximate
∆T
of
40°C without core loss. Derating is necessary for AC currents. It is recommended
that the temperature of the part not exceed 125°C under worst case operating
conditions verified in the end application.
3) Isat Amperes Peak for approximately 30% rolloff @ 20°C
4) Applied Volt-Time product (V-µS) across the inductor. This value represents the
applied V-µS at 200kHz necessary to generate a core loss equal to 10% of the
total losses for 40°C temperature rise. See Core Loss Graph.
Units supplied in tape & reel packaging; 250 parts on 13" diameter reel.
