PTC resettable fuses are useful devices which are used for protecting electrical circuits against overloads and short circuits. They come in various voltage and current ratings, and the most common type of PTC resettable fuse is the YQS8119.

The YQS8119 is a thermally activated resettable fuse which is designed to protect electronic circuits from overcurrent and short circuit conditions. It can be used in a wide variety of applications, including consumer electronics such as digital cameras, computers, and phones, and industrial electronics such as control systems and automation equipment.

The YQS8119 has a wide operating temperature range (from -40°C to +85°C) and can be used in a variety of environments, including high-temperature applications. It is UL and CSA certified for safety, and it is RoHS compliant. It is also designed to meet the requirements of FCC Part 15 EMC and safety standards.

The YQS8119 is a self-resetting fuse with a thermal-activated element. It features a triode design which enables it to protect against both overcurrent and short circuit conditions. When the current exceeds the rated current of the fuse, the thermal-activated element becomes heated and the fuse trips, thus interrupting the circuit and protecting it from overloads or short circuits.

When the current reduces, the thermal-activated element cools down and the circuit is restored. This feature allows the YQS8119 to be reset multiple times until the problem is solved. The fuse also features an indicator which shows the status of the circuit; green indicator shows it is safe to operate, while red indicator indicates a fault has occurred.

The YQS8119 is a reliable device which is designed to provide protection against both overcurrent and short circuit conditions. Its thermal-activated element allows it to be reset multiple times and its wide operating temperature range makes it suitable for a variety of environments.

It is UL and CSA certified for safety, and meets the requirements of FCC Part 15 EMC and safety standards. The fuse is also RoHS compliant, making it a safe and reliable device for protecting electrical circuits against overloads and short circuits.
