PTC Resettable Fuses are electronic components which are used to protect against dangerous currents flowing through electrical circuits. The CMF-RL35-0 is a type of PTC Resettable Fuse, designed for use in low voltage, energy-restricted applications. This type of fuse is relatively recent, and is growing in popularity due to its many benefits.

The CMF-RL35-0 is a self-resetting, polymeric positive temperature coefficient (PPTC) PTC Resettable Fuse. It operates similar to a thermal fuse by opening up when an over-current situation is detected, but it can be "reset" by simply cycling the voltage, while a thermal fuse cannot be used again. This makes the CMF-RL35-0 a practical choice for protecting against over-current situations.

The CMF-RL35-0 application field consists of mostly low voltage, high safety applications. These include industrial automation and control systems, medical devices, battery packs, and similar applications.

In order to understand how the CMF-RL35-0 works, we must first understand how it is designed. The fuse consists of two main components: a "resettable" element and a "trigger" element. The resettable element is made up of a polymeric substrate and two positively-charged electrodes. The electrodes are connected in series with the supply current and act as a "compliant" element.

The trigger element is a temperature-sensitive resistor, which is connected in parallel with the resettable element. When the current through the circuit exceeds the specified threshold, the temperature-sensitive resistor heats up, and triggers the resilient element to open, disconnecting the current flowing through the circuit. The current is then interrupted until the circuit is reset, which is usually done by simply cycling the voltage.

Once the voltage is cycled, the resistor cools down and the resettable element is closed again. This allows the current to resume flowing through the circuit. The CMF-RL35-0 can prevent over-current situations from causing damage to the device it is protecting.

The CMF-RL35-0 is an excellent choice for applications which require a reliable, self-resetting PTC Resettable Fuse. Its two-component design makes it highly effective at preventing dangerous over-current situations, making it an ideal choice for low voltage, energy-restricted applications.
