CTCR32F Series
From 1.0 µH to 390 µH
RoHS
Compliant
Not shown at actual size.
CHARACTERISTICS
Description: SMD power inductor
Applications: VTR power supplies, OA equipment, LCD
televisions, PC notebooks, portable communication equipment,
DC/DC converters
Operating Temperature: -30°C to +100°C
Inductance Tolerance: ±20%
Testing: Inductance is tested on an HP4284A or HP4285A at
specified frequency
Packaging: Tape & Reel
Marking: Marked with inductance code
Rated DC: This indicates the value of current when the
inductance is 10% lower than its initial value at D.C.
superimposition or D.C. current when at ΔT=40°C, whichever is
lower.
Miscellaneous: RoHS Compliant.
Additional Information: Additional electrical & physical
information available upon request
Samples available. See website for ordering information.
