A3281LLHLT Overview
The magnetic switch is packaged in the Tape & Reel (TR) in order to prevent damage. For safety reasons, magnetic switches are packaged in SOT-23W packages. For good performance, magnetic switches can supply 8mA as their maximum current. To be output, magnetic switches must have a maximum current of 25mA. 3 terminations are contained in it. It should supply a maximum voltage of 24V when it is functioning. When this switch is in a reliable operating state, it typically supplies 12V voltage. This magnetic switch can provide 4.2V voltage as the minimum voltage.
