Description
RoHS
2002/95/EC
• 155°C maximum total temperature operation
• Surface mount inductors designed for high speed,
high current switch mode applications requiring
lower inductance
• Gapped ferrite cores for maximum efficiency
• Inductance values from 0.100 uH to 0.200 uH
• Current range up to 64 Amps
• Meets UL 94V-0 flammability standard
• Ferrite core material
Applications
• Voltage regulator modules (VRMs) for servers,
microprocessors
• High frequency, high current switching power supplies
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.

4) DC current for an approximate ∆T of 40°C without core loss. Derating is
necessary for AC currents. PCB layout, trace thickness and width, airflow, and
proximity of other heat generating components will affect the temperature rise. It
is recommended that the temperature of the part not exceed 155°C under worst
case operating conditions verified in the end application.
5) Peak Current for approximately 30% rolloff @ 20°C
1) Units supplied in Tape & Reel packaging; 900 parts on 13" diameter reel.
2) OCL (Open Circuit Inductance) Test parameters: 1MHz, .100Vrms,
0.0Adc & ISAT @20°C
3) Applied Volt-Time product (V-µS) across the inductor. This value represents the
applied V-µS at 500kHz necessary to generate a core loss equal to 10% of the
total losses for 40°C temperature rise.
