difference between time delay and fast acting fuse

　　Precautions for using plastic encapsulated patch varistor fuses

　　1. Proper selection and installation are necessary to ensure its proper functioning. During use, do not arbitrarily change the parameters of PPTC to avoid damage to components and equipment.

　　2. Long term work in environments such as high temperature, humidity, corrosion, and electromagnetic interference should be avoided to avoid affecting the mechanical and electrical characteristics of PPTC.

　　3. After the temperature rises and triggers, it takes a certain amount of time to return to the low resistance state. Therefore, if there are circuits that require continuous operation, sufficient time needs to be reserved to wait for PPTC to recover.

　　4. The work that needs to be matched with other components and equipment in the circuit, especially considering compatibility with components such as power supply and circuit protection.

　　In summary, plastic encapsulated surface mount varistors have important application value as circuit protection components. For the correct selection and use of plastic encapsulated surface mount varistors, we need to understand their various parameters and related knowledge as much as possible to effectively protect the safety and stable operation of circuits and equipment.
