• PTC Resettable Fuses
• PTR016V0135-BK Application Field and Working Principle
  • Application Field
  • PTR016V0135-BK PTC Resettable Fuses are widely used to protect circuits from over current, over voltage and short circuit conditions. The fuses have small physical dimensions and can be used for both AC and DC applications. The most common applications include cell phones, computers, electronic appliances, power adapters, portable electronic devices, automotive systems, and LED lighting systems. This type of fuse also helps to reduce labor costs by simplifying the maintenance process.
  • Working Principle
  • PTR016V0135-BK PTC Resettable Fuses work on the principle of thermal expansion and contraction. When a certain current flows through the fuse, the PTC material inside the fuse heats up and expands. As the temperature increases, the resistance of the doped PTC material also increases, thereby restricting further flow of current. When the current exceeds the rated value, the PTC material reaches its maximum temperature and stops further flow of current. This prevents any damage due to excessive current flow.
  • When the current decreases to its normal level, the material cools down and contracts. This reduces the resistance, allowing normal current flow. The PTC Resettable Fuses are particularly useful in situations where frequent current fluctuations are expected, as they can protect the device from both over-current and under-current. Furthermore, it reduces the need for frequent maintenance of the fuse, which simplifies the maintenance process.
  • Overall, the PTR016V0135-BK PTC Resettable Fuses are compatible with current electronics needs as they provide reliable protection from potential damages due to over-current and short circuit conditions. In addition, they are also easy to install and greatly reduce labor costs.
