This value represents the HC7-XXX-R applied V-S at operating frequency necessary to generate additional core loss HC7 = Product code and size which contributes to the 40C temperature rise. De-rating of the Irms is required XXX = Inductance value in uH. to prevent excessive temperature rise. The 100% V-uS rating is equivalent to a R = Decimal point. If no R is present, third character = of zeros ripple current Ip-p of 20% of Isat (30% rolloff option). -R suffix indicates RoHS compliant It is recommended that the temperature of the part not exceed 155C under worst case operating conditions verified in the end application.
