PTC Thermistors are temperature sensors which are categorized under the broad category of thermistors. Thermistors are temperature sensitive elements that can detect the minimal changes in the environment. In the category of PTC thermistors, PTCCL21H202DBE has a wide range of applications and works diligently to detect even the minutest of changes in the environment. It is ideal for temperature control in various devices as it has good accuracy.

It has an operating range from -50°C to 150°C and maximum change in resistance up to 80 %. It consists of two terminals which connect to a resistor with wires. The resistor is composed of a special material which is known to change resistivity with temperature. This is known as a positive temperature coefficient (PTC) element. As the temperature around it increases, the resistance of this element also increases.

PTCCL21H202DBE has immense application potential. It can be used as an over-temperature protection device in the surface area of milling machines, welding lamps, air conditioners, refrigerators, electric water heaters, computers, as well as other household appliances. In addition to this, it can also be used as a safety device in soaping, plating, hydraulic equipment, and drying processes.

This device works on the principle of electromigration. In simple words, this is a process in which the movement of ions in a conductor is affected by the presence of an electric field. The electric field causes the ions to move from one place to another, creating a change in the electrical properties of the material. With respect to PTCCL21H202DBE, the electric field is created by the temperature difference between the two terminals of the device. When the temperature increases, the electric field is stronger and causes the ions to move towards the negative terminal, leading to an increase in the resistance of the device.

PTCCL21H202DBE is a reliable device for sensing temperature with greater accuracy. Its ability to provide over-temperature protection in a working environment makes it the ideal choice for many industrial applications. It is composed of a special material that can change its resistance in response to a rising temperature, making it a useful tool for temperature control.
