PTC Resettable Fuses

Polymeric Positive Temperature Coefficient Resettable Fuses (PTCs) are electronic components that are primarily used for protecting circuits from overloads and short-circuits. The SMD260-2 is a special type of PTC fuse that is designed for low voltage, medium current applications. It is generally used in electronics applications such as consumer electronics, medical devices, automotive electronics, and communications.

The SMD260-2 is a metal oxide varistor (MOV), which is made up of a composite of three special materials: zinc oxide, silicic acid and glass frit. These materials provide the SMD260-2 with its unique ability to abruptly increase resistance when it reaches a certain temperature via the "positivity of temperature coefficient" characteristic.

Because of this, the SMD260-2 is able to convert its high thermal tolerance into mechanical energy and quickly open the circuit. This is what makes it such a useful and reliable component for protecting circuits from unwanted overloads and short-circuits. Upon cooling, the SMD260-2 will immediately reset and return to its normal state, allowing the circuit to remain working normally after the overload has been removed.

The SMD260-2 provides a high moisture resistance and low temperature coefficient. This makes it especially well-suited for applications in high-humidity environments, such as outdoor electronics. Its low temperature coefficient allows for precise and stable cutoff operation in cold environments, making it suitable for a wide range of environmental conditions.

In addition, the SMD260-2 offers a low profile design and is available in low cost, flexible packaging. This allows for efficient integration into consumer electronics and other products. It is also easy to assemble in automated and manual processes and has long product life-span.

In summary, the SMD260-2 is an efficient and reliable component for protecting circuits from overloads and short-circuits. It is designed for low voltage, medium current applications and is especially well-suited for use in high-humidity environments, such as outdoor electronics. Its low temperature coefficient also allows for precise and stable cutoff operation in cold environments, making it suitable for a wide range of environmental conditions. Furthermore, it offers a low profile design and is available in low cost, flexible packaging, making it easy to integrate into a variety of products.
