A3214LLHLT Overview
The magnetic switch is packaged in Tape & Reel (TR) to protect it from damage. In order to prevent damage to the magnetic switches, they are packaged in SOT-23W packages. In order to perform well, magnetic switches can provide a maximum current of 2mA. If these switches work, they can output 1mA as the maximum current. To make the switches work, they have 3 pins. In total, 3 terminations have been recorded. Switches like this should supply voltages no higher than 5.5V. In most cases, this switch will supply 3V voltage to ensure relability. This magnetic switch can supply a voltage as low as 2.4V.
