PTC Resettable Fuses (< acronym title="Positive Temperature Coefficient">PTC) are electronic devices that provide reliable and efficient over-current protection. They are used in many different applications and are generally preferred over traditional fuses due to their ability to reset themselves after an over-current event, so that they can continue to provide over-current protection without having to be replaced. The RUSB075 is a PTC fuse that can be used in a wide range of applications and offers reliable over-current protection. In this article, we will discuss the application field and working principle of the RUSB075.

Application Field of the RUSB075

The RUSB075 is a robust and versatile PTC resettable fuse. It is designed to withstand a wide range of temperatures, from -40°C to +125°C, and it is able to handle high levels of over-current for long periods of time. As such, it is ideal for use in a variety of areas. For instance, it is often used for data lines and power supplies in industrial, automotive, military, and consumer electronics applications. It can also be used for over-current protection in medical applications, network systems, and audio systems.

Working Principle of the RUSB075

The RUSB075 is a current-sensing device that is able to detect and limit over-current events. When a normal current is flowing through the device, it will remain in a low-resistance, “on” state. However, when an over-current event is detected, the device will transition to a high-resistance, “off” state. This will effectively limit the flow of current through the device, thus preventing further damage from occurring. The RUSB075 is also able to reset itself after the over-current event has been resolved. It will automatically transition back to its low-resistance, “on” state, thus allowing it to continue to provide reliable over-current protection.

In addition, the RUSB075 also offers additional protection against over-voltage and over-temperature events. It is designed to limit the voltage that passes through it in order to prevent damage to the system from excessive voltage, and it also has temperature-sensing capabilities that can detect when temperatures have exceed safe limits and shut off the device. This makes the RUSB075 an ideal choice for use in applications where over-current, over-voltage, and over-temperature protection are required.

Conclusion

The RUSB075 is a versatile and reliable PTC resettable fuse that can be used in a wide range of applications. It offers reliable over-current protection, shutting off the flow of current when an over-current event is detected, and it can reset itself once the over-current event has been resolved. Additionally, the RUSB075 also offers protection against over-voltage and over-temperature events. As such, it is an ideal choice for use in any application requiring over-current, over-voltage, and over-temperature protection.
