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 0.5m

Ω. The EBWB can handle

a constant power of 7W at 0.2m

Ω and a continuous

load of 180A at 0.2m

Ω.
