PTC Resettable FusesPTC resettable fuses are popular electrical components that are widely used to provide circuit protection in a variety of applications. The YQD120N0015 is a particularly popular model, and it offers all the benefits of a PTC resettable fuse in a small and cost-effective package.In this article, we will take a look at the application field and working principle behind the YQD120N0015 PTC resettable fuse, and how it makes it such a useful component in various electrical systems.The YQD120N0015 is a PTC resettable fuse designed for use in a range of high-current and high-voltage circuits. It is usually used for input power switch, power adapter, machine control systems, AC/DC motor protection, LED lighting, and solar systems.The YQD120N0015 is designed to be highly resistant to overloads and extends the life of the system by automatically limiting the current that flows through it. It also features an integrated short-circuit protection mechanism, which ensures that any short circuit is quickly detected and the associated circuit is automatically shut down before any damage is done.The YQD120N0015 is a self-healing device that is able to detect and recover from any over-current situation. It achieves this by using a polymeric positive temperature coefficient (PPTC) device, which consists of semiconducting polymer material that can respond to changes in temperature.When a certain level of over-current is detected, the PPTC will expand, disrupting the current flow and thus activating the fuse. At this point, the PPTC device will be completely shut off and will begin to cool down. When it has cooled down to a certain temperature, the PPTC device will return to its original state and the circuit will be restored, allowing the system to be used again.The YQD120N0015 also features built-in high surge capability, allowing it to withstand higher transient voltage spikes on its input and output. This makes it suitable for use in a range of different applications, where it can provide the necessary protection against surges and other electrical faults.Overall, the YQD120N0015 is a highly optimized and reliable PTC resettable fuse, which offers excellent protection and performance in a wide range of applications. It is easy to install and requires little maintenance, making it a cost-effective and reliable protection solution for a variety of applications.
