EBWA-MR0005FET

EBW Series Manganin/Aluchrom Alloy Current Sense 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 temperatures 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. c e r t i f i c at i o n s BN ES ISO 9001: 2008 ISO/TS 16949: 2009 A p p l i c at i o n s • Current sensors for hybrid power sources • Frequency converters • High current automotive applications.
