The EBW Series are manufactured using electron
beam welding technology. This allows the joining of
different alloys with great accuracy and tolerance.
The EBW Series have heavy copper connectors,
excellent long term stability and low inductance.
These components can tolerate soldering tempera-
tures of 350C for 30 seconds or 250C for 10min.
These can be mounted using re-flow soldering or
welding on copper. The EBWA can handle a power
of 5W up to 100A at 0.5mΩ. The EBWB can handle
a constant power of 7W at 0.2mΩ and a continuous
load of 180A at 0.2mΩ.
