TDK SPM magnetic shield type wound inductors

Mixed Media

TDK SPM magnetic shield type wound Inductors for power circuits are a low-profile product lineup with maximum heights of 1.2mm, 1.5mm, 2.0mm, and 3.0mm, allowing for different usages. Compared to ferrite wound type inductors, TDK SPM inductors allow designers to achieve large current, low RDC, and compactness. These inductors also feature 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.
