λ Bridge Thermal Conductor
A\/X’s new λ-Bridge Thermal Conductor is manufactured with the highest
quality materials for reliable and repeatable performance providing a cost
effective thermal management solution. These devices are constructed
with Aluminum Nitride (AlN) or Beryllium Oxide (BeO) and are available in
standard EIA form factors.
λ-Bridge provides the designer with the ability to manage thermal conditions
by directing heat to a thermal ground plane, heat sink or any other specific
thermal point of interest. The inherently low capacitance makes this device
virtually transparent at RF/microwave frequencies. This device has the added
benefit of offering additional layers of protection to adjacent components from
hot spot thermal loads.
λ-Bridge provides the benefit of increased overall circuit reliability. A\/X’s λ-Bridge is manufactured using one-piece
construction, providing a RoHS compliant SMT package that is fully compatible with high speed automated pick-and-
place processing. It is available in 0302, 0402, 0603 and 0805 EIA case sizes. Custom configurations are also available.
