A1221ELHLT-T Overview


In order to prevent damage, the magnetic switch is packaged in the Tape & Reel (TR). Magnet switches are packed in SOT-23W packages for safety reasons. When these switches are working, their maximum current will be 25mA. There is a maximum current that can be supplied by these switches of 4mA. Switches require 3 pins to function. Generally, switches should output 25mA current.
