:PTC Resettable Fuses
PTC Resettable Fuses are an important form of protection for electronics circuitry and their components, providing an essential form of circuit protection, while also allowing the user to easily recover from unexpected service disruptions. The PTC Resettable Fuse (or also known as PPTC, Polymeric Positive Temperature Coefficient) is a polymeric element whose resistance increases with increasing temperature. They can act as a thermal protection device, protecting the system from over-current, over-voltage, and over temperature. This article will discuss the application field and working principle of the PTCTT95R250GTE.
Application Field
The application field of PTC Resettable Fuses is vast. These devices can be used in, but not limited to, low-voltage automotive protection, industrial applications, white goods protection, medical equipment protection, datacom/telecom circuits protection, battery-management, power supplies, video game consoles and audio equipment, consumer electronics, LED lighting and many more. They are ideal for protection circuits in areas with limited space and active cooling. They have the advantages of fast auto-reset, small size, stable operation, high reliability and replaceable.
Working Principle
The working principle of PTC Resettable Fuses is based on the temperature dependent resistance of the materials used. When a PTC reaches a maximum temperature, their resistance increases to a level, which is so high that it stops the current. It remains in this high resistance state until the temperature is lowered by removing the source of heat. This resetting occurs as a result of the underlying material\'s physical properties. When the temperature cools, the resistance decreases, enabling the current to flow again.
The duty cycle of a PTC Resettable Fuse varies by the type of device. Some activates at a temperature as low as 10°C and others as high as 150°C. For example, the PTCTT95R250GTE is designed to protect circuits from over-current and over-temperature. It has a fast and sensitive reaction, with trip time of 2.0s at a current of 250A and a hold current at 150A. At a temperature of 149°C, it has a resistance of 10-30 KΩ.
Conclusion
PTC Resettable Fuses are an important form of protection for electronics circuitry and their components, providing an essential form of circuit protection, while also allowing the user to easily recover from unexpected service disruptions.
The PTCTT95R250GTE is designed for a wide range of applications and offers an effective over-temperature and over-current protection solution. Its fast and sensitive reaction make it a reliable device in a wide range of temperatures and load currents.
