A3214LLHLT-T Overview


A protective Tape & Reel (TR) is applied to the magnetic switch in order to prevent damage. In order to ensure safety, magnetic switches are packaged in SOT-23W packages. The magnetic switches can supply 2mA as the maximum current for good performance. In its maximum state, these switches can output 1mA. 3 pins are used to operate the switches. As far as terminations are concerned, there are 3. Generally, switches should output 1mA current. The maximum voltage supplied by this switch should be 5.5V when it works. In normal conditions, this switch will deliver 3V voltage. The minimum voltage that can be supplied by this magnetic switch is 2.4V. During operation, the magnetic switches may supply a voltage of 3V.
