HIGH CURRENT 2™
Power Inductors
Description
• 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: -40C to +125C
• Operating ambient temperature range: -40C to +85C
(range is application specific).
• Infrared reflow temperature: +260C for 10 seconds
maximum

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.

Packaging
• 45 parts per tray bulk packaging.
• Tape and reel packaging also available, 44mm width,
110 parts per 13" reel.
• Add -TR after part number for tape and reel packaging.
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.
