PTC Resettable Fuses
16R300GU application field and working principle
PTC resettable fuses, also known as polymeric positive temperature coefficient (PPTC) fuses, are a type of fuse used for over-current protection applications. They are resettable, meaning that when the fuses open they can be reset after the fault is eliminated and the fuses will return to their normal working state. The 16R300GU series is one of the most popular resettable fuse and is available in many industry standard sizes and amperage ratings, making it an ideal choice for a variety of different applications including board-level power protection, motor protection, battery protection, and all types of general purpose protection.
The working principle of the 16R300GU series PTC resettable fuse is based on the temperature dependence of a specialized polymer material. When the current passing through the material exceeds the rated amperage, the temperature of the fuse will start to rise until it reaches the PTC reset temperature. At this temperature, the polymer material will drastically increase its resistance and stop the current flow. Once the fault is eliminated and the temperatures drop to a certain level, the resistance of the material will drop and allow the current to flow again, resetting the fuse.
The 16R300GU series PTC resettable fuse is designed for use in a variety of different applications. It can be used in power protection for all types of board-level components, including motherboards, hard drives, memory modules, and more. It is also ideal for motor protection and battery protection, as it is able to protect the motor or battery from dangerous levels of over-current. In all types of general purpose protection applications where an economical yet reliable solution is needed, the 16R300GU series can be a great choice.
The 16R300GU series of PTC resettable fuse offers several key features that make it an ideal solution for a variety of different applications. It is highly reliable, has a fast response time, and is highly resistant to shock and vibration. Additionally, it is cost-effective and easy to install, making it an ideal choice for any application where over-current protection is required.
The 16R300GU series PTC resettable fuse is a reliable, cost-effective over-current protection solution for a variety of applications. It is easy to install and provides fast response times, making it an ideal solution for board-level power protection, motor protection, battery protection, and any other type of general purpose protection. Additionally, it is highly resistant to shock and vibration, making it reliable and dependable for all types of applications.
