TDK, SPM, 4012 Shielded Wire-wound SMD Inductor with a Metallic Magnetic Core, 2.2 μH ±20% Wire-Wound 3.3A Idc

SPM4012 Series magnetic shield type wound inductor for power circuits use a metallic magnetic material
SPMSPM4012 series structure has an integrated moulded coil, so hum noise is lower than with core adhesive coils
They have a low-profile with maximum heights of 1.2mm and 3.0mm allowing for different usages
Possible to achieve large current, low Rdc, and compactness
Low inductance variance in high-temperature environments with good DC superimposition characteristics
