The SPM-LR series 4012 type from TDK are commercial grade magnetic shield type wire wound inductors for power circuits using a metallic magnetic material.
Inductance value range from 0.47µH to 4.7µH
Low profile product
Maximum DCR value range from 17.6mohm to 196.7mohm, Isat current range from 3.3A to 8.5A
Low inductance variance in high temperature environments with good DC superimposition characteristic
Inductive tolerance of ±20%
Operating temperature range from -40°C to +125°C
Compared to ferrite wound type inductors, possible to achieve large current, low Rdc and compactness
