Cooper FP3-1R0-R Low profile inductor Datasheet

FLAT-PAC™ 3
Low Profile Inductors
Description
RoHS
2002/95/EC
• 155°C maximum total temperature operation
• Low profile high current inductors
• Inductance range 0.1uh to 15uh
• Design utilizes high temperature powder iron material with a
non-organic binder to eliminate thermal aging
• Current rating up to 34.7Adc (Higher peak currents may be
attained with a greater rolloff, see rolloff curve)
• Frequency range up to 2MHz
Applications
• Computers and portable power devices
• Energy storage applications
• DC-DC converters
• Input - Output filer application
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) OCL (Open Circuit Inductance) Test parameters: 100kHz, 0.1Vrms, 0.0Adc
2) DC current for an approximate ∆T 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 155°C under
worst case operating conditions verified in the end application.

5) K-factor: Used to determine B p-p for core loss (see graph). B p-p =K*L*∆I
B p-p:(Gauss), K: (K factor from table), L: (Inductance in uH), ∆I (Peak to peak
ripple current in Amps).
