PTC (Positive Temperature Coefficient) Resettable Fuses are widely used in many areas due to their safety and dependability - such as consumer electronics, medical, and other industries. One of the most popular versions of PTC Resettable Fuses is the SMD1206P100TFA fuse, which is a widely used in both consumer and industrial applications.

SMD1206P100TFA is an axial leaded, 4.5mm (0.177") pitch resettable fuse, available in a standard 12.5mm (0.5") long, with a continuous current rating of 100mA. As a PTC fuse, the current that the SMD1206P100TFA can handle is limited and if the current surpasses the rating, the fuse\'s resistance will increase sharply, thus limiting the current to the rated value. This feature makes the PTC Resettable Fuses highly reliable and very suitable for consumer and security applications which need safety and dependability.

The design and working principle of the SMD1206P100TFA Resettable Fuse is quite simple and reliable. The fuse itself is composed of a plastic body, containing a polymer disc, and two sets of conductive rods. The polymer disc has a high temperature coefficient of resistance, which means that when the current flows through the fuse, the resistance of the disc will increase, thus limiting the current to the set level. This is a purely mechanical design and highly reliable.

The SMD1206P100TFA Resettable Fuse is designed to be used in a wide range of power supplies, from very low power applications, up to 100mA continuous, making it a very versatile and dependable product. It is suitable for a wide range of applications such as over-voltage protection, short-circuit protection, current limit protection, over temperature protection, and many more.

One of the main advantages of the SMD1206P100TFA Resettable Fuse is its convenience and safety. The fuse does not require a fuse holder, which makes it simple to install. It is also much safer than a conventional fuse, because it can reset itself instead of having to be replaced each time the circuit is tripped.

The design and working principle of the SMD1206P100TFA Resettable Fuse make it a very versatile and reliable product, which is suitable for a wide range of applications. It is highly reliable and easy to install, making it the perfect choice for safety-critical applications.
