FP3-R10-R Datasheet, PDF (1/3 Pages) Cooper Bussmann, Inc. – 155°C maximum total temperature operation Low profile high current inductors

FLAT-PAC™ 3
Low Profile Inductors
Description
• 155°C maximum total temperature operation
RoHS
2002/95/EC
• 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.
Packaging
• Units supplied in tape and reel packaging.
Reel quantity = 1,700 parts per reel.

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.
