Derating from table), L: (inductance in μH), ΔI (peak-to-peak ripple current in amps). 6 Part Number Definition: HCP0704-xxx-R • HCP0704 = Product code and size • xxx= Inductance value in μH, R = decimal point. If no “R” is present, then third character = # of zeros • “-R” suffix = RoHS compliant is necessary for AC currents. PCB pad layout, trace thickness and width, air-flow and proximity of other heat generating components will affect the temperature rise. It is recommended the part temperature not exceed +125 °C under worst case operating conditions verified in the end application.
