PTC Resettable Fuses

A PTC resettable fuse, often referred to as a polyfuse, is a special type of thermal fuse. These devices are used to protect electronic circuits from being exposed to overcurrents. The PTC resetable fuse has a positive temperature coefficient which causes it to heat up when an overload current is applied and cut off the circuit, protecting the circuit from any further damage. In addition, these devices also have a thermal resettable feature which enables them to reset after a overcurrent situation has been removed.

The RGEF1100 is a specifically designed resettable fuse used in a wide variety of applications ranging from consumer electronics to industrial, automotive, and medical applications. It is designed to protect circuits from overcurrents up to 0.95A and is resetable up to a temperature of 95° C. The device is ideal for use in applications where the overcurrent is intermittent or short-term and can trip very quickly.

Working Principle

The working principle of the RGEF1100 resettable fuse is based on the principle of positive temperature coefficient. This means that when an overcurrent passes through the device, its internal temperature will rise. At a level above 95° C, the device will trip and cut off the circuit. This action protects the components in the circuit from any further damage. After the overcurrent situation has been removed, the device will reset and allow the current to pass through again.

The design of the PTC resettable fuse helps to ensure that the component is safe and reliable during normal use. The device has a high temperature resistance rating so it can handle the heat generated by short-term overloads without permanent damage. It also has a low internal resistance which helps ensure that the protection is not compromised by too much current being forced through it.

Application Field

The RGEF1100 resettable fuse has a wide range of applications in various fields. These devices are commonly used in consumer electronics, such as automotive sound systems, laptop chargers, and home audio systems. They are also used in industrial and medical applications, such as in automotive electronics, power formers, switching power supplies, and medical equipment.

The use of these devices in industrial applications is increasing due to their ability to protect critical equipment from overcurrents. The device is ideal for use in applications where the overcurrent is intermittent or short-term. This includes applications such as motor controllers, power supplies, and other high power equipment. Additionally, the device can be used to protect circuits from interference and from other potential damages.

The RGEF1100 resettable fuse is an excellent device for a wide variety of applications. Its low power rating, high temperature resistivity, and easy resetting make it a great choice for protecting sensitive electronic circuits. The device is also highly reliable, easy to install, and simple to use, making it an ideal solution for many applications.
