A3281LLTTR-T Overview

This Tape & Reel (TR) package protects the magnetic switch from damage. In order to prevent damage to the magnetic switches, they are packaged in TO-243AA packages. A magnetic switch can supply a maximum current of 8mA if it is well designed. For magnetic switches, the maximum current should be 25mA. This document contains 3 terminations. When this switch is functioning, its maximum voltage should be 24V. Normally, this switch will supply 12V voltage for reliable performance. This magnetic switch can supply a voltage as low as 4.2V.
