The SMD2018P150TF PTC resettable fuse manufactured by Ruilongyuan is a surface mount device (SMD) component with a maximum power dissipation of 150 amperes. It is RoHS-compliant and features a temperature monitoring function. This PTC fuse is used in applications such as automotive, computing, communications, consumer electronics, and medical devices for over-current and over-temperature protection. The device requires minimal board space and is easily mounted on the printed circuit board (PCB). It also has an integrated ESD protection structure and low leakage current design. The SMD2018P150TF PTC fuse provides fast response time to over-currents and is designed for reliable operation in applications subject to reverse voltage, high temperature cycling, and vibration.
