SPM-LR series

SPM4020-LR type

FEATURES

Magnetic shield type wound inductor for power circuits using a metallic magnetic material.

Low-profile product.

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.

Operating temperature range: –40 to +125 °C (including self-temperature rise)

APPLICATION

Tablet terminals, note PCs, HDDs, servers, VRMs, compact power supply modules, other

Application guides: Smart phones/tablets
