TDK-EPC, a group company of TDK Corporation, has extended the range of its standard ERU series of power inductors with the EPCOS ERU 20 series. These new components are characterized by a particularly high current capability. At inductance values of between 1.0 and 35.0 µH, the ERU 20 chokes possess a current capability of between 9.3 and 50.0 A. Their DC resistance values range between 0.62 and 7.0 mΩ.
As a result these ERU inductors are particularly suitable for use in high-current low-voltage DC-DC converters, point-of-load converters (POL) and multiphase modules. Their design is based on optimized ferrite cores and flat-wire winding technology. Their low core losses and self-supporting winding permit an excellent energy storage density as well as very compact dimensions. Thus, the ERU 20 inductors have a footprint of only 21 x 21.5 mm2 and an insertion height of between 9.8 and 14.2 mm, depending on the type. The components are RoHS-compatible and can also be manufactured in customer-specific versions.
Possible applications are the power supplies of telecommunications and IT systems as well as inverters for photovoltaic systems.
- Power supplies of telecommunications and IT systems as well as photovoltaic systems.
Main features and benefits
