SPM-LR Series Inductors

TDK introduces their SPM-LR series commercial grade power inductors

Image of TDK SPM-LR Series InductorsTDK’s SPM-LR series power inductors are magnetically shielded, wire-wound inductors designed for use in power circuits. Their low profile makes them ideal for use in applications where height is restricted. The SPM-LR series has low inductance variance in high temperature environments with good DC superimposition characteristics and achieves large current, low RDC, and compactness compared to ferritewound type inductors. A metallic magnetic material is used and the structure has an integrated molded coil so hum noise is lower with the SPM-LR series inductors than with core adhesive coils. The SPM-LR series also has a redesigned terminal construction, based mainly on material change, and has a DCR improvement anywhere from 4% to 50% depending on case size and inductance value as compared with its predecessor SPM series.
