PTC Resettable Fuses are an electronic component found in a wide range of devices, from consumer electronics, to cars, to medical equipment. They are used to protect sensitive electronic components from damage due to power surges or overheating. The SMDH120-2 is a type of PTC Resettable Fuses that offers a high level of protection for high current applications.

The SMDH120-2 device works on the principle of thermal protection. It contains a polymeric Positive Temperature Coefficient (PTC) device which can detect excessive temperature. The temperature of the device rises when high current is flowing through it, causing the PTC to change its resistance abruptly and trigger an overtemperature protection mechanism. The device is designed to repeatedly reset after the current drops back to normal levels. This ensures that the flow of current does not remain disrupted, while still providing protection from excessive currents or thermal events.

The SMDH120-2 PTC Resettable Fuses are used in a variety of applications requiring high current protection. These include automotive systems, battery packs, industrial and consumer products, medical diagnostic equipment, smart meters, LED lighting, and power electronics. In automotive systems, they are used to protect the vehicle\'s wiring systems from short circuits, excessive current, or voltage spikes. In battery packs, they are used to protect battery cells or packs from overcharging or excessive currents. In medical equipment, they are used to protect against high voltage from electricity-conducting components such as cables and leads.

The SMDH120-2 PTC Resettable Fuses are designed for maximum safety and reliability in high-current applications. The device\'s ability to repeatedly reset after an overcurrent or overtemperature event is what makes it ideal for protecting sensitive electronic components. Also, the device has a very low Cold Resistance, allowing it to reduce its resistance significantly under high-current loads, ensuring that the current is passed uninterrupted. This makes it a very reliable fuse for high-current applications.

The SMDH120-2 provides an effective solution for protecting sensitive electronic components from overheating and excessive current. Its high-current protection, ability to reset after an overcurrent or overtemperature event, and low Cold Resistance make it an ideal choice for a wide variety of applications, ranging from automotive systems and battery packs, to medical and commercial devices, to LED lighting and power electronics.
