This low-profile design is based on a flat rectangular helical winding technology which results in lower losses. The DC resistances are between 1.05 mΩ and 15.35 mΩ. With the new ERU16 types TDK is expanding its broad spectrum of ERU SMT power inductors, which include the existing ERU13, ERU19, ERU20 and ERU25 series.
The new series of high-current chokes is designed for operating temperatures of between -40°C and +150°C. Its additional third soldering pad results in high mechanical stability on the PCB. They can be used as output and storage chokes in a wide variety of power supply topologies.
These include point-of-load (POL) converters, DC/DC converters, high-current switch-mode power supplies, solar converters and xEV applications. The components of the new series are RoHS-compatible and qualified to AEC-Q200.
