PTC Resettable Fuses are a form of overcurrent protection ideal for consumer and computer applications. The 0ZCG0300FF2B in particular is a surfacemount, polymeric positive temperature coefficient device with a high current rating of up to 0.3A.

The 0ZCG0300FF2B exhibits a low initiation current of just 0.29A and has a quick response time of 2-4 milliseconds. Additionally, the 0ZCG0300FF2B offers reliable protection in the event of overcurrents, with a 105° breaking capacity at a ±10% operating temperature range. When triggered, the device trips at a significantly higher current than its initiation current, rendering it suitable for sensitive circuitry.

The 0ZCG0300FF2B finds its primary application field in consumer and computer applications such as phones, tablets, and other compact peripherals. Its small size and surface mounting make it particularly suited for these applications. The 0ZCG0300FF2B is also suitable for protected circuits in automotive applications.

The 0ZCG0300FF2B works on the principle of thermally-sensitive electrical resistance. Its behavior is such that a sudden increase in the temperature of its sensitive element will lead to the rapid increase of its resistance. In the event of an overload, the thermal resistance rapidly increases, leading to the current limitation and triping of the fuse.

Once triggered, the thermal element will rapidly cool down, leading to a decrease in its resistance. As the temperature approaches the normal electrical operating temperature, the resistance decreases and the device becomes reset. However, in the interest of safety, the fuse must be replaced in order to ensure that it is not unintentionally reset.

Overall, the 0ZCG0300FF2B PTC Resettable Fuse is an ideal solution for overcurrent protection in consumer and computer applications. Its quick response time and reliable protection make it an excellent choice for equipment that needs to be protected from potential overloads.
