A1221LLHLX-T Overview
The magnetic switch is packaged in Tape & Reel (TR) to protect it from damage. SOT-23W packages are used for safety reasons to protect magnetic switches. Switches of this type are capable of delivering 25mA as the maximum current when they are in use. They can supply up to 4mA amps of current. In order for the switches to function, they have pins 3. This termination has 3 terminations. Switches should generally output a current of 25mA.
