|
|
• 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)
