A3280LLTTR-T Overview
Magnetic switches are packaged in Tape & Reel (TR) to prevent damage. In order to ensure the safety of the magnetic switches, they are packaged in TO-243AA packages. The magnetic switches can supply 8mA as the maximum current for good performance. When operating, these switches can output a maximum current of 25mA. For magnetic switches, the maximum output current should be 25mA. A magnetic switch can be set to 150°C for its maximum operating temperature. This magnetic switch, however, must be operational at a temperature greater than -40°C.
