A1221LLHLX-T Overview
In order to prevent damage, the magnetic switch is packaged in the Tape & Reel (TR). SOT-23W packages are used to protect the magnetic switches from damage. The maximum current that can be output by these switches is 25mA. There is a maximum current that can be supplied by these switches of 4mA. There are 3 pins on the switches that allow them to work. It contains 3 terminations. It is generally recommended that the switches output 25mA current.
