TDK has expanded its EPCOS ERU SMT power inductor portfolio with the ERU19 choke series, which includes ten different types. The inductance of the new ERU chokes has been extended from 1.0µH to 30µH, and its saturation current ranges from 10.1ADC to 43ADC.
The outstanding feature of these new power inductors is their compact design: their dimensions are only 19.9mm x 20.5mm, and their insertion heights are as low as 8.35mm (1.0µH) to 10.85mm (30µH), depending on the type. This low profile design is based on flat rectangular spiral winding technology to reduce losses. The DC resistance is between 1.20mohm and 18.65mohm.
B82559 * A019 series high current chokes are designed for operating temperatures from -40 ° C to + 150 ° C. They can be used as output and storage chokes in various power topologies. These include point-of-load (POL) converters, DC-DC converters, high-current switch-mode power supplies, and xEV applications. The new series of components are RoHS compliant and will soon be AEC-Q200 certified.
Typical applications include point-of-load (POL) converters, DC-DC converters, high-current switch-mode power supplies, and output and storage chokes for xEV applications.
