HIGH CURRENT 2™
Power Inductors
Description
RoHS
2002/95/EC
• Compact footprint for high density, high
current/low voltage applications
• Foil technology that adds higher reliability factor
over the traditional magnet wire used for higher
frequency circuit designs
• Frequency Range up to 1MHz
Applications
• Next generation microprocessors
• Energy storage applications
• DC-DC converters
• Computers
Environmental Data
• Storage temperature range: -40°C to +125°C
• Operating ambient temperature range: -40°C to +85°C
(range is application specific).
• Solder reflow temperature: +260°C for 10 seconds

1) Open Circuit Inductance Test Parameters: 300kHz, 0.250 Vrms, 0.0 Adc
2) DC current for an approximate temperature change of 40°C without core loss.
Derating is necessary for AC currents.
PCB layout, trace thickness and width, air-flow and proximity of other heat
generating components will affect the temperature rise.
It is recommended that the temperature of the part not exceed 125°C under
worst case operating conditions verified in the end application.
3) Peak current for approximately 30% roll-off
4) Values @ 20°C
5) Applied Volt-Time product (V-µS) across the inductor. This value represents the
applied V-µS at 300KHz necessary to generate a core loss equal to 10% of the
total losses for 40°C temperature rise.
