PTC (Positive Temperature Coefficient) resettable fuses are relatively small polymeric devices which are used to protect electronic circuits from overcurrents. The PTC resettable fuse, such as CMF-RL35A-0, are particularly advantageous over standard circuit protection devices, such as thermal cutoffs or fuses, in that they can automatically reset without replacing the fuse or disconnecting the circuit. This allows the device to be used repeatedly without manually resetting the fuse or disabling the protection. Due to their superior protection characteristics, PTC resettable fuses are becoming increasingly popular in the current market.

The CMF-RL35A-0 resettable fuse can be used in a variety of industries, from automotive to consumer electronics. It is particularly beneficial in applications where the circuit must be re-enabled quickly and the risk of additional overpowering is low. When the power load current, whether it is AC or DC, exceeds the rated current, the fuse will heat up due to its internal resistance, causing it to open and cut off the current. The fuse must then be physically reset to restore power. This resetting action allows the device to be reused multiple times without having to replace the fuse.

The CMF-RL35A-0 also offers a wide range of features, which make it an excellent choice for many applications. The wide range of operating temperatures, ranging from -55°C to +120°C, the tight leakage tolerance of 0.5μA, and the short circuiting current of 30A make this product suitable for use in automotive, consumer, and industrial applications. In addition, the device is highly reliable and includes features such as low temperature operation, high temperature stability, and overvoltage protection. The compact size of the device, combined with its low weight, also makes it well suited for use in space-constrained, high-current applications.

Understanding the working principle of the CMF-RL35A-0 resettable fuse is important for its successful application. In normal circumstances, the fuse acts as an open circuit, which does not conduct current. When the current through the device exceeds a certain limit, the fuse heats up due to its internal thermal resistance. This heats up the internal polymeric composition of the device which causes it to expand and open the circuit. When the current drops below the threshold limit, the fuse cools and the polymeric composition contracts, allowing the circuit to be reset and the device to be reused.

PTC resettable fuses like the CMF-RL35A-0 have become the preferred choice for many applications, due to their ability to automatically reset without sacrificing protection. This allows greater efficiency and reliability for some applications where the risk of overloading the circuit is a potential danger. The wide range of features and operating temperatures make the CMF-RL35A-0 an ideal choice for automotive, consumer, and industrial applications. The working principle of the CMF-RL35A-0 is based on the thermal resistance of the device, which increases when exposed to higher current levels, causing it to expand and open the circuit.
