PTC resettable fuses, also called Polymer Positive Temperature Coefficient resettable fuses, are self-resetting devices that protect against electric overload problems. They provide an effective and reliable protection against devices and circuits against threats of external overloads, such as electric shorts and power surges. PTC Resettable Fuses, also known as Polymer Positive Temperature Coefficient Resettable Fuses, are essential in protecting sensitive electronic devices.

The major benefits of these PTC fuses are that they are self-resetting, meaning they reset themselves automatically when an overload or surge is detected. This helps to minimize the amount of downtime and keeps the device or circuit from being ruined by the surge. They also have very low resistance compared to other types of fuses. This reduces the amount of power they use and helps to keep electricity costs low.

The Model 250S130DR PTC Resettable Fuse, which is a typical resettable fuse, is a self-resetting fuse with a wide operating temperature range of -55 to 125 °C. It is RoHS compliant and has a reset voltage of 130V AC/DC. It has a current rating of 250mA and can also be used to protect sensitive electronic devices from voltage spikes or surges. It has an activation time of 1.7seconds and a reset time of less than one millisecond.

The Model 250S130DR PTC Resettable Fuse has a wide range of applications. It can be used to provide reliable protection for LED lights, household appliances, industrial electronics, consumer electronics, and other sensitive electronic devices. It is also commonly used in automotive, marine, and other outdoor applications due to its waterproof design.

The working principle of the Model 250S130DR PTC Resettable Fuse is based on the PTC effect. It is a semiconductor device that uses the PTC effect to function. When an overload or surge is detected, the PTC device heats up due to the current flowing through it. As the temperature rises, its resistance also rises, thus limiting the amount of current flowing through the fuse, thereby protecting the device from the overload. When the current stops flowing, the PTC device cools down and its resistance goes back to its original state, resetting the fuse.

In conclusion, the Model 250S130DR PTC Resettable Fuse is a reliable, self-resetting device with a wide range of applications. Its working principle is based on the PTC effect and it provides effective protection against external overloads. It is waterproof and has a wide operating temperature range, making it suitable for use in a variety of settings. It is an economical and reliable way to protect sensitive electronic devices from voltage surges and overloads.
