1) Test Parameters: 100KHz, 1.0Vrms
It is recommended that the temperature of the part not exceed 155°C under worst
case operating conditions verified in the end application.
2) Irms Amperes for approximately ΔT of 40°C above 85°C ambient
3) Isat Amperes Peak for approximately 15% rolloff (@20°C)
4) Isat Amperes Peak for approximately 30% rolloff (@20°C)
Part number definition:
HC8-XXX-R
HC8 = Product code and size
XXX = Inductance value in uH.
R = Decimal point. If no R is present, third character = #of zeros
-R suffix indicates RoHS compliant
5) Applied Volt-Time product (V-μS) across the inductor. This value represents the
applied V-μS at operating frequency necessary to generate additional core loss
which contributes to the 40°C temperature rise. De-rating of the Irms is required
to prevent excessive temperature rise. The 100% V-uS rating is equivalent to a
ripple current Ip-p of 20% of Isat (30% rolloff option).
