Ohmite BA1160 Aluminum cased resistor Datasheet

BA Series
Aluminum Cased Resistor
Our Aluminum housed brake
resistors are designed for high
power and provide great stability. These resistors are constructed using wirewound on
ceramic cores and isolated using
a mica sheet for high dielectric
properties. The aluminum house
is filled with a high thermal conductivity material to ensure quick
heat dissipation during continues applications. With the ability
to have a thermal cut off switch
embedded inside the aluminum
housing, makes the BA series
ideal for any safety application.
