Highly efficient power inductors for automotive applicationsTDK-EPC Corporation has developed the VLM13580-D1 and DR SMD power inductors with extended operating temperature range and increased rated current.

Thus, the new TDK power inductors are suitable for use as choke coils in the DC-DC converters of automotive engine control units (ECU).

Components used in automotive electronics applications are exposed to severe environmental conditions. For this reason, TDK-EPC has improved the heat resistance properties of the VLM13580-D1 and DR series of SMD power inductors power inductors. They can now be used at a temperature range from -40 °C to +150 °C. In addition, the use of a ferrite core with low loss and improved DC superimposition characteristics achieves much higher efficiency. The new series feature a much higher rated current. For example, the new VLM13580T-2R2M-D1 is rated at 20 A (maximum) versus 15 A (maximum) of the existing VLM10555T-2R5M8R0-2H types.

The product lineup comprises eight components (six D1 products and two DR products) with various inductances.

Applications include Choke coil in the DC-DC converters of automotive engine control units and other components.

Mass production of the D1 and DR specification inductors is scheduled to begin in October 2011. For further information, contact [email protected]eu.tdk.com
