PTC Resettable Fuses are a type of fuse used in a variety of different electronic applications. They are often referred to as resetable fuses, polyfuses, positive temperature coefficient (PTC) fuses, self-resetting fuses, or PPTCs. These fuses are made up of two main components: a PTC element and a trip mechanism. The PTC element acts as a resistive element and will heat up when the current through it reaches a certain limit. The trip mechanism is made up of a bi-metal disc that breaks the circuit when it is heated by the PTC element above a certain temperature. This prevents the fuse from continuing to draw current when it has reached its maximum load.

SMD1206P035TFA is one of the most commonly used PTC Resettable Fuses. It is a 1206-size surface mount device (SMD) with a 35 Amp current rating. The set current rating of the device is 6 Amps and a hold current rating of 2.3 Amps. It has a temperature coefficient of +25ppm/˚C and an operating temperature range of -40˚C to +85˚C.

SMD1206P035TFA is mainly used as voltage protection devices for over-voltage and over-current conditions. When current exceeds the hold current rating, the PTC element heats up and the trip mechanism is activated, breaking the circuit and preventing further damage to the circuit. The device can be reset by simply removing and reapplying power to the circuit. Once the over-voltage or over-current condition has been removed, the PTC element will cool down to its normal operating temperature, allowing the circuit to be reset.

The advantages of using SMD1206P035TFA as a PTC Resettable Fuse are many. They are small and lightweight, making them easy to install in tight spaces. They are also inexpensive, making them ideal for applications where cost is a factor. Additionally, since they are self-resetting devices, it saves time and effort on maintenance visits. Finally, they provide excellent protection from dangerous over-voltage and over-current conditions.

In summary, SMD1206P035TFA is a 1206-size surface mount device (SMD) with a 35 Amp current rating and is one of the most commonly used PTC Resettable Fuses. It is mainly used as voltage protection devices for over-voltage and over-current conditions and has many advantages, such as being small and lightweight, inexpensive, self-resetting, and providing excellent protection from dangerous over-voltage and over-current conditions.
