The SDF DF072S is a thermal cutoff, commonly known as a thermal fuse, that performs the primary role of safety control in a variety of electrical appliances. Its primary purpose is to protect the appliance and its users from damage caused by overheating. It features two metal discs, each containing a thermally sensitive material that melts at a predetermined temperature. When the internal temperature of the appliance reaches or exceeds the predetermined temperature, the thermally sensitive material melts, causing the two metal discs to separate, thus breaking the electrical circuit and stopping the flow of electricity through the appliance.

Given this function, thermal cutoffs are often found in many household appliances, such as coffee makers, toasters, microwaves, hair dryers, and washing machines. They can also be found in a range of industrial and automotive electrical appliances, such as production machinery or in-vehicle electronic control units. Thermal cutoffs are also used in a range of electronic products, including computers, game consoles, and phones, to protect them from excess heat.

The SDF DF072S is a bimetal thermal cutoff designed for high temperature applications. It features a small disc composed of two metal layers that bond together during production. One layer is composed of a high-conductivity alloy and the other alloy is a low-conductivity metal. These metals bond together in such a way that when the predetermined temperature is exceeded, the higher-conductivity metal expands faster than the low-conductivity metal, thus causing the disc to snap and the electrical connection to break.

The SDF DF072S also offers a wide range of temperature ratings. Depending on the model, the temperature ratings range from 32°C to 240°C and higher. It is capable of cutting off current flows as low as 15 mA and is effective even when exposed to large temperature fluctuations. Additionally, the SDF DF072S offers a wide range of current ratings, ranging from 2.1A to 3A. This makes it suitable for use in various types of appliances.

In addition to its safety functions, the SDF DF072S also offers a range of other features making it a useful and versatile thermal cutoff. It is resistant to vibration and impact, making it suitable for use in high vibration and shock applications. It has a wide operating range, allowing it to work in a wide range of environmental conditions. Additionally, it has a long life expectancy thanks to its robust design and reliable construction.

The SDF DF072S is a reliable and efficient thermal cutoff that provides a range of functions for a variety of electrical and electronic applications. Its ability to cut off current flows quickly and reliably helps to ensure the safety of the appliance and its users, while its wide range of temperature and current ratings ensure it can be used in a variety of applications. Thanks to its reliable construction and robust design, the SDF DF072S offers a long life and high performance.
