CMF-SDP35-2

PTC Resettable Fuses, also known as polymeric positive temperature coefficient fuses, are highly reliable electronic devices used to protect devices from over-current and over-voltage. They are used to disconnect or shunt electric current circuit when current is too high. CMF-SDP35-2 is a type of polymeric positive temperature coefficient fuse that can be used in a wide range of applications.The working principle of the CMF-SDP35-2 is based on the property of polymers to increase electrical conductivity when exposed to heat. If the current passing through the fuse is too high, the heat generated in the fuse will be higher than normal and it will cause the polymers in the fuse to conduct more electricity. This will trip the circuit and disconnect it from the rest of the system, thus protecting it from over-current and over-voltage.The CMF-SDP35-2 can be used in a variety of applications such as cell phone chargers, home automation systems, and automotive electronics, etc. It is unique because it is designed to cut off the current automatically in the event of a power surge. Moreover, it is self-resettable, which means that it can be reset and reused multiple times. This makes it an ideal choice for any application that needs an automatic over-current protection.The CMF-SDP35-2 is made up of two sets of components – a conductive polymer film and a copper foil layer. The conductive polymer film helps in the thermal disconnection during an over-current event, while the copper foil layer serves as a current path between the two leads. The copper foil layer also helps to evenly distribute the heat generated due to excessive current. Furthermore, the CMF-SDP35-2 has a metal cap that protects it from mechanical damage. The CMF-SDP35-2 can be used in portable electronic devices such as mobile phones, tablets, and laptops. It can also be used in home automation systems to prevent equipment damages due to a short circuit or power surge. Since it is self-resettable, it also helps to save time and money by not requiring any manual resetting.In conclusion, the CMF-SDP35-2 is a perfect example of a PTC resettable fuse which can provide protection against over-current and over-voltage in a wide range of applications. It is lightweight, self-resettable, and easy to install. Furthermore, it does not require manual resetting, which makes it a cost effective solution.
