PTC Resettable Fuses are self-resetting molded body fuses which are nowadays widely used in a variety of electronic circuits for protecting against thermal or overload issues. SMD150-2 is one of these fuses which uses a modified version of the polymeric positive temperature coefficient (PPTC) structure. SMD150-2 has a wide application range within the electronic circuits and it works in the following principle.

Generally, the working principle of PTC Resettable Fuses is based on the fact that when a current passes through them, as it goes higher than a certain threshold, they increase their resistance. This increase of resistance causes a heating effect which eventually interrupts the flow of current, making them act as a thermal control. That is why these fuses are employed in those circuits where the current can reach an unsafe level.

SMD150-2 is quite specialized in comparison to other PTC Resettable Fuses, and has some advantages which makes it a preferred choice for certain applications. It has a response time which is significantly shorter than that of other fuses, often allowing for a more rapid response to an overload issue. It also has an extremely low resistive temperature coefficient which allows it to remain stable over a range of temperatures. In addition, the melt temperature of the SMD150-2 is higher than the typical PTC Resettable Fuses. This also contributes to increased reliability across a broader range of applications.

After tripping, the SMD150-2 can be reset with a power cycle or a simple manual reset, and it will resume its normal operation. It is often used in equipment which has a high-demand rate, like power supplies, transport equipment, anti-theft systems, and automotive electronics. Many times the SMD150-2 is used for over-current protection in cables due to its current limitation and resistor functions. By limiting the current, it reduces damage to the equipment and increases the safety of the system.

The main application of this particular PTC Resettable Fuse is in low voltage, low power applications such as computer peripheral and communications equipment, consumer electronics, home appliances, and automotive electronics. Its high current limiting capability and low power and resistance make it a preferred choice for those applications which require over-current protection. Its resettable structure makes it a much better choice compared to traditional fuses as it can be reset quickly and easily when the problem is solved. It also does not require frequent replacement and therefore saves time and money in the long run.

SMD150-2 PTC Resettable Fuses are an important element in many electronic applications and circuits and have proven to be a reliable device for over-current protection. Its special features such as fast response time, low temperature coefficient, and high current limiting capability make it a favorable choice when deciding on the protection of electronic components and systems.
