PTC (Positive Temperature Coefficient) Resettable Fuses have become an increasingly popular form of circuit protection due to their ability to respond quickly to short-circuit situations. In particular, the LTP190 series of PTC Resettable Fuses has developed a reputation as a reliable and cost-effective solution for personnel protection especially when used in industrial, automotive and consumer applications. In this article, we will provide an overview of the applications and working principles of the LTP190 series PTC Resettable Fuses.

One of the key advantages of the LTP190 series of PTC Resettable Fuses is its ability to be used in a wide variety of applications. The device is particularly well suited for personnel protection, and is often used in applications such as automotive fuses, infrared heaters, blade fuses and consumer electronics. Furthermore, the device can also be used in medical devices, industrial equipment, home appliances and other similar applications. In addition, the device is able to provide protection against voltage surges and DC current, and can also inhibit arcs in AC applications, providing an additional layer of protection.

In order to understand the specific capabilities of the LTP190 series PTC Resettable Fuses, it is important to understand the working principle of the device. Essentially, the LTP190 series uses a special thermistor that responds to an increase in temperature. The device works by utilizing a positive temperature coefficient, meaning that the resistance of the device increases as the temperature increases. In response to a voltage surge or an increase in current, the device’s resistance will increase, thereby blocking the current and preventing a short-circuit. The device is then able to automatically reset itself after the temperature has returned to normal, enabling it to be used again.

The LTP190 series PTC Resettable Fuses are particularly well suited for use in applications which require short-circuit protection, such as industrial, automotive and consumer electronics. The device is able to provide quick and reliable protection, while also reducing the potential for damage that can result from short-circuit situations. Furthermore, the device is able to reset itself automatically, allowing for increased reliability and longevity. As such, the LTP190 series PTC Resettable Fuses are the perfect solution for personnel protection, allowing users to utilize the device in a wide variety of applications with confidence.
