• Current range from 29 Amps to 1.8 Amps
• Frequency range 1kHz to 500kHz
Applications
• Next generation processors
• High current DC-DC converters
• VRM, multi-phase buck regulator
• PC Workstations, Routers, Servers
• Telecom soft switches, Base stations
Environmental Data

1) Open Circuit Inductance test parameters: 100KHz, 1.0V, 0.0Adc
2) Irms: DC current for an approximate DT of 40°C without core loss. Derating is
necessary for AC currents. PCB layout, trace thickness and width, air-flow, and prox-
imity of other heat generating components will affect the temperature rise. It is rec-
ommended that the temperature of the part not exceed 155°C under worst case
operating conditions verified in the end application.
3) Isat Amperes Peak for approximately 15% rolloff (@20°C)
4) Isat Amperes Peak for approximately 30% rolloff (@20°C)
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).
Part number definition:
HC8LP-xxx-R
HC8LP = Product code and size
xxx = Inductance in μH. R = decimal point.
If no R is present third character = # of zeros.
-R suffix indicates RoHS compliant
