TDK-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
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
