.
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.

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.
5) Part number definition - HC1-xxx-R:
• HC1 = Product code and size
• -xxx = Inductance value
• R = Decimal point (if no “R” is present,
third character = number of zeros)
• -R Suffix = RoHS compliant
