A1143ELHLT-T Overview
An integrated magnetic switch is packaged within the Tape & Reel (TR) in order to protect it against damage. For safety reasons, magnetic switches are packaged in SOT-23W packages. The magnetic switches are capable of supplying 17mA as their maximum current. Switches require 3 pins to function. It contains 3 terminations. This switch should supply a maximum voltage of 24V when it is in operation. It is normal for this switch to supply 12V in order to perform reliably.
