PTC (Positive Temperature Coefficient) resettable fuses are a type of electronic component used to protect electronic circuits from short circuit overloads. They are also known as Polymeric Positive Temperature Coefficient Devices, or PPTCs. The AGRF800-2 belongs to this family of devices, and it combines two main features: thermal and electrical protection. This device is widely used in the automotive, telecom, medical and industrial sectors, and it provides reliable circuit protection while maintaining high reliability and safety.

The way the AGRF800-2 works is by combining two distinct elements: thermistor and resistor. The thermistor is responsible for detecting any over-current situation, and then the resistor element initiates the breaking of the circuit when the pre-defined trip level is reached. This allows the circuit to be deactivated and the user is then able to reset the device, if necessary, to regain the desired operation. The AGRF800-2 also incorporates a temperature-compensated thermal fuse, which adds extra safety in the event of an over-current situation. This further protects the users and their circuits from any over-heating that could lead to damage or, in some cases, even fire.

In application field, the AGRF800-2 is often used in various consumer electronics, such as power supplies, notebooks and PCs, street lights, game consoles, solar lights, and electric vehicles. It is also available as a surface mount component, allowing it to be easily integrated into various products. In the automotive sector, the AGRF800-2 is used in applications such as anti-theft systems, airbag modules, and door locks. It is also often used in circuits where the current flow must be monitored or limited in order to ensure safe operation.

Moreover, the AGRF800-2 provides a reliable surge protection that responds quickly to excessive currents and provides reliable protection against accidental short-circuit or over-voltage situations. It is particularly well-suited for environment with extreme temperatures and humidity condition. Furthermore, due to its compact size and low resistance, it can be used extensively without compromising design flexibility or space.

In conclusion, the AGRF800-2 is a highly reliable and versatile resettable fuse. It has a wide range of applications in a variety of fields, including in the automotive, telecom, medical, and industrial sectors. Its combination of thermal and electrical protection makes it an ideal choice for protecting circuits from over-current situations and providing reliable surge protection against short-circuiting and over-voltage scenarios. Furthermore, it is a cost-effective solution due to its compact size and low resistance, making it ideal for applications where space and design flexibility are a concern. As such, the AGRF800-2 has become a widely used and popular choice for circuit protection.
