SPM3020 -CA Series
SMD Power Inductor
a) Small Footprint and Low Profile Design :
Footprint : 3.2 x 3.0 mm Typ.
Height : 2.0mm Max.
b) High Power Handling Capability :
Small Copper Loss
Using Large Saturation Induction of
Fe- based metals
c) Flat inductance performance over temperature
based on the high curie temperature of the iron
powder core material.
d) Automatic Mounting in Tape&Reel Package.
