文档预览
HC8 Series
HIGH CURRENT 8
Power Inductors
Description
RoHS
2002/95/EC
• Surface mount inductors, 4.0mm height,
designed for higher speed switch mode
applications requiring low voltage and high current
• 155°C maximum total operating temperature
• Design utilizes high temperature powder iron material
with a non-organic binder to eliminate thermal aging
• Inductance offering expanded for applications
requiring higher inductance.
• Inductance Range from 0.175 uH to 47.3 uH
• Current Range from 39.0 to 2.4 Amps
• Frequency Range 1kHz to 500kHz
Applications
• Next generation microprocessors
• High current DC-DC converters
• VRM, multi-phase buck regulator
• PC, Workstations, Routers
• Telecom soft switches, Base Stations
Environmental Data
• Storage temperature range: -40°C to +155°C
• Operating ambient temperature range: -40°C to +155°C
(range is application specific)
• Solder reflow temperature: +260°C max. for 10 seconds
max.

1) Test Parameters: 100KHz, 1.0Vrms
2) Irms Amperes for approximately
∆T
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)
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).
It is recommended that the temperature of the part not exceed 155°C under worst
case operating conditions verified in the end application.
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
