PTC resettable fuses are increasingly popular in the safety field. They are designed to be used in small, low-power applications where a little extra protection is needed. SMDC075F-2 is one such popular resettable fuse. It is widely used in many commercial military and industrial applications. In this article, we will discuss about the SMDC075F-2 application field and working principle.

The SMDC075F-2 can be used as over-voltage and overload protection for various types of electronic devices. It has a low profile, so it can be integrated easily into tight spaces. This resettable fuse can handle up to 75V and up to 7A of current. It is designed to protect against surges, overloads, and short circuits. This resettable fuse is also capable of resetting quickly after an overload, making it ideal for high-frequency applications. It is also UL1449 certified, making it suitable for use in hazardous locations.

The SMDC075F-2 is essentially an electrically operated one-time fuse. It has two pins, the cathode and the anode. When a specific voltage is applied across the two pins, the fuse is activated. Due to current flowing through the fuse, the resistance increases to a certain point, and the current flow is cut off. When the voltage is removed, the resistance slowly decreases to its original state and the current flow is resumed.

When a voltage greater than the rated one is applied to the SMDC075F-2, the fuse will switch from a low-resistance state to a high-resistance state. This effectively cuts off all current flow and the device is protected against an overload. Once the current is reduced to a safe value, the SMDC075F-2 will gradually return to its original low-resistance state, allowing current to flow once again. Additionally, the fuse has an internal trigger which protects the device against short circuits by quickly disconnecting the circuit.

The SMDC075F-2 application field continues to expand as it has become increasingly popular for over-voltage and overload protection. It’s found in a broad range of applications such as LED lighting, telecommunications, 3D printers, electric vehicles, and heavy industrial equipment. Its UL1449 certification ensures that the device is suitable for safely operating in hazardous locations. In addition, its low profile and quick resetting capabilities make it perfect for small, low-power applications.

In conclusion, the SMDC075F-2 resettable fuse is widely used for over-voltage and overload protection in a variety of applications. Its low profile and UL1449 certified features enable it to be safely used in hazardous locations. Furthermore, its quick resetting capabilities make it perfect for both high-frequency and low-power applications. Thus, with its many benefits, it is no surprise that the SMDC075F-2 is one of the most popular resettable fuses on the market.
