ERU-SMT Power Inductors
TDK extends its wide range of compact SMT high-current chokes
TDK Corporation has extended its range of EPCOS ERU-SMT power inductors with the ERU19, ERU24 and ERU27 (B82559*) series. These devices are comprised of up to ten types, covering an inductance value range of 1.0 µH to 30 µH. The range of saturation currents that are covered includes 11.5 ADC to 101.5 ADC at +25°C. These power inductors offer a compact design with a footprint of 19.9 mm x 18.5 mm to 27.8 mm x 25.8 mm taking up 14% less space on the printed circuit board (PCB) than their predecessor. The low insertion heights vary between 7.65 mm and 16.9 mm depending on the type. This low-profile design is based on a flat rectangular helical winding technology, resulting in lower losses.
The ohmic resistances are between 0.46 mΩ and 17.0 mΩ. These high-current chokes are designed for the operating temperature range of -40°C and +150°C. The product’s additional third soldering pad contributes to high mechanical stability on the PCB. These inductors are RoHS-compatible and AEC-Q200 qualified, making them suitable for output and storage chokes in a wide variety of power supply topologies. The ERU-SMT power inductors are suitable for use cases including point-of-load (POL) converters, DC/DC converters, high-current switch-mode power supplies, and inverters for photovoltaic systems and automotive applications.
