Thermal Cutoffs (Thermal Fuses) are an important class of safety devices which protect electric circuits against overheating and overcurrent. They are designed to switch off power supply when abnormally high temperatures or overcurrents are detected. The most commonly used Thermal Cutoff is the SDF DF100S.

The SDF DF100S is a thermal cutoff device which is designed to detect overcurrents or temperatures in an electronic circuit. It is a small component, usually measuring only a few millimeters in size, and contains a hermetically sealed metallic, ceramic or plastic tube filled with gas. When a current or temperature level is exceeded, the gas inside the tube will expand, pressure will build up and a switch will be triggered which will shut off power to the circuit.

The SDF DF100S is usually mounted on a heat sink or circuit board inside an electrical device. It can be used as a primary or secondary protection against overcurrents and overheating. It can also be connected to a thermal switch to provide additional protection against overheating. The SDF DF100S is a diode type protection device and can be used in low voltage applications up to 1.5 volts.

The SDF DF100S thermal cutoff device has a number of advantages over other types of Thermal Cutoffs. It is easy to install and requires minimal maintenance, and can withstand temperatures up to 500°C. It also has a wide range of handling current, making it well suited for powering a variety of electronic devices. The unique design of the SDF DF100S also offers high levels of reliability and repeatability.

The SDF DF100S thermal cutoff device works by monitoring the temperature or current in a circuit, and if either of these levels exceed a pre-set limit, the device will switch off the power supply. This safety feature helps to ensure that electronic devices will not be damaged due to excessive heat or overcurrent. The SDF DF100S is designed to be fail-safe, meaning that if it fails, it will disconnect the power supply, protecting the device and the circuit from overloads.

The SDF DF100S is used in a wide variety of applications, including consumer electronics, industrial and medical equipment, and automotive applications. It is an ideal choice for protecting sensitive electronics from damage due to excessive heat or overcurrent. It also provides high reliability and low cost, making it attractive for a variety of applications.
