A1212ELHLT-T Overview
For protection against damage, the magnetic switch is packaged in the Tape & Reel (TR). In order to prevent damage to the magnetic switches, they are packaged in SOT-23W packages. The magnetic switches can supply a maximum current of 7.5mA for good performance. Switches of this type are capable of delivering 25mA as the maximum current when they are in use. 3 pins are used to operate the switches. This document has 3 terminations.
