A1214LLHLT-T Overview
A protective Tape & Reel (TR) package is used to protect the magnetic switch against damage. In order to ensure safety, magnetic switches are packaged in SOT-23W packages. In their operating mode, these switches can output a maximum current of 25mA. Currents up to 7.5mA can be supplied by these switches. There are 3 pins on the switches that allow them to work. The file contains 3 terminations. It is generally recommended that the switches output 20mA current.
