Inductors for power circuits
Wound metal
SPM series
SPM12565XT type
FEATURES
Magnetic shield type wound inductor for power circuits using a metallic magnetic material.
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
Power supply around the CPU, HDDs, servers, VRMs, compact power supply modules, other
PART NUMBER CONSTRUCTION
CHARACTERISTICS SPECIFICATION TABLE
Rated current: smaller value of either Isat or Itemp.
Isat: When based on the inductance change rate (20% below the initial value)
Itemp: When based on the temperature increase (temperature increase of 40°C by self heating)
・The cleaning agent can not be used for these products.
Measurement equipment
＊ Equivalent measurement equipment may be used.
TEMPERATURE RANGE, INDIVIDUAL WEIGHT
Operating temperature range includes self-temperature rise.
The storage temperature range is for after the assembly.
