Inductors for Power Circuits
Wound Metallic Magnetic Material
Product compatible with RoHS directive
Halogen-free
Compatible with lead-free solders
Overview of the SPM Series
FEATURES
Magnetic shield type wound inductor for power circuits using a metallic magnetic material.
Low-profile product lineup with max. heights of 1.2mm and 3.0mm allowing for different usages.
Compared to ferrite wound type inductors, it is possible to achieve large current, low Rdc, and compactness.
Low inductance variance in high-temperature environments with good DC superimposition characteristics.
Metallic magnetic material is used, and the structure has an integrated molded coil, so hum noise is lower than with core adhesive coils.
APPLICATION
Smart phones, tablet terminals, laptop computers, HDDs, servers, VRMs, compact power supply modules, other
