The Yageo SMD1206B050TF/15 PPTC Resettable Fuses with 15V 0.5A PPTC SMD 1206 is a surface-mountable, resettable overcurrent protection device. It provides protection for a wide range of applications, including consumer electronics, auto, telecommunications, power supplies, LED drivers, and more. The device features a 1206 case size, rated for 15V and 0.5A current, and is composed of positive-temperature-coefficient (PTC) thermistor material to provide overcurrent protection. The fuse is designed to automatically trip and break the circuit when an overcurrent event occurs. Once the current is restored to normal levels, the device automatically resets and restores current flow. This PTC device provides reliable overcurrent protection while allowing for easy, time-saving installation and long-term use.
