BA Aluminum Cased Resistors

Ohmite BA Aluminum Cased Resistors are high-power wirewound components that offer multiple wattages up to 1KW with heatsink capability. These resistors are constructed using wirewound with 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 continuous applications. The ability to have a thermal cut-off switch embedded inside the aluminum housing makes the BA series ideal for any safety application. Three extrusion forms, thermal cut-off, and scalable, custom lengths/leads are all available with the ruggedly designed resistors.
