PTC Resettable Fuses are electrical protection devices whose resistance rises drastically when an over-current passes through them. AHRF070 is one of such products, and it is a polymeric positive temperature coefficient (PPTC) device which can protect any electrical and electronic equipment from short-circuits and current overloads. As the name implies, when an over-current passes through the fuse, its resistance increases quickly and effectively to regulate the current levels, even while the fault is still present. The current limitation of the fuse allows it to avoid any damage to the equipment or system.
AHRF070 Application Field
AHRF070 is suitable for any application where reliable, continuous, and flexible protection is needed. It is usually used to protect any system from short circuits and over-currents, while maintaining regulated current levels. Typical AHRF070 applications includes computers, cash registers, telecommunications equipment, automotive and other electronic components, power converters, medical equipment, displays, and more. It is also suitable for applications requiring isolation, such as PCMCIA slots, USB ports and other microsockets.Working Principle
The basic working principle behind the AHRF070 is based on a highly reliable polymeric Positive Temperature Coefficient (PPTC) device which will both trip and reset the fuse. This device measures resistance in order to regulate current levels. When the current flow is above the fuse’s rated current, the fuse resistance rises from a low level to a higher level in order to limit the current. This process is known as tripping, whereas the PPTC device disconnects the power supply in order to prevent any further current flow. After the excess current is removed, the PPTC device is reset and power is restored.Advantages
AHRF070 offers many advantages to its users compared to other fuse solutions. It is much more reliable, as it can effectively regulate current levels and protect from current overloads and short circuits. Furthermore, the protection provided is continuous and does not need any resetting or replacement. Additionally, the PPTC parent material is highly resistant to moisture and can easily cool off in any environment.The AHRF070 also provides users with a much simpler solution compared to other fuses. This makes it easy to install and use, and it also can provide a much lower profile that is suitable for any given application.Conclusion
In conclusion, AHRF070 is a reliable and efficient PPTC fuse suitable for any application that requires it. It offers users a more flexible and simple solution that is perfect for protecting from any short-circuits and over-currents. This fuse is both resilient and easy to install, and it can provide continuous protection for any electronic equipment or system.The specific data is subject to PDF, and the above content is for reference
