PTC Resettable Fuses, also known as Polymeric Positive Temperature Coefficient (PPTC) devices, are self-resetting overcurrent protection devices. They are widely used in consumer electronics and a wide variety of industrial and commercial applications. The SMD100F-2018-2 is one of these devices and is designed to protect equipment and circuits from the hazards of overcurrent and excessive surge currents.

The working principle of the SMD100F-2018-2 is based on a PTC polymer, which alters its resistance characteristics when exposed to overcurrent and excess heat. Technically, the device is formed by depositing a film of positive temperature coefficient (PTC) polymeric material across an I/O metal substrate. When the current flows through the SMD100F-2018-2, the resistance of the PTC material begins to increase as the current increases. When the current exceeds the rated current of the fuse, it triggers the in-built internal temperature sensing element. This causes the resistance of the PTC material to sharply increase, thus reducing the current to a safe level. Once the overcurrent situation is resolved, the PTC material returns to its normal low resistance state, allowing the device to reset itself and the system to return to a normal state.

The SMD100F-2018-2 is widely used in a variety of applications such as power supplies, consumer electronics, appliances, communications, industrial control, automotive electronics and other applications. In addition to providing overcurrent protection, the device also has an empty circuit indication feature which indicates the presence of an open circuit or lack of current in the system. This feature helps to protect against accidental equipment damage caused by open circuits.

The SMD100F-2018-2 also has several additional features that make it an ideal choice for a wide range of applications. It has an extremely fast response time, one of the lowest trip point ratings available on the market, and it has a high inrush current handling capability. It also has a high temperature rating of up to 125°C, making it suitable for use in harsh environments. Additionally, the SMD100F-2018-2 has an improved self-resetting feature, which makes it more reliable than other PTC resettable fuses.

Overall, the SMD100F-2018-2 is a reliable and effective PTC Resettable Fuse suitable for a wide range of applications. It is easy to install, highly durable and has several additional features and benefits that make it an ideal choice for protecting a range of equipment and circuits from overcurrent and excessive surge currents.
