PTC resettable fuses are an important component used in many electrical, automotive, and electronic systems and products. They are designed to protect circuits from overloads and to provide reliability and safety to users. The 1812L125ZR PTC resettable fuse is one of the most commonly used models in the market today.

This particular model is a low voltage overcurrent protection component with thermally self-resetting features. It is designed for use in systems with a maximum voltage of 125V at 18A. The protection rating is over 1000A at 5 seconds and 10A at 1 hour. It is a compact size fuse with a total weight of only 3 grams and features UL recognized components.

The 1812L125ZR model offers excellent protection against electrical spikes or short circuits and overvoltage protection. It is suitable for many applications such as LED lighting systems, electric motors, UPS systems, power supplies, household appliances, and so on. The fuse is designed to quickly open when an overload occurs and then reset automatically once the current returns to normal. This ensures that the circuit can be safely restarted without causing any damage.

The working principle of this particular model is based on the PTC resettable fuse technology. This technology uses a special polymer material that changes its resistance with changing current. When the current passes through the fuse, the polymer expands and creates enough resistance to open the circuit. The resetting process begins when the current passes through the fuse again and the polymer slowly contracts, allowing the current to flow through the circuit safely.

The 1812L125ZR PTC resettable fuse is a reliable protection component that is ideal for a variety of applications. It is designed to quickly open when an overload occurs and reset itself once the current returns to normal. This ensures that the circuit can be safely restarted without causing any damage. The working principle is based on the PTC resettable fuse technology which uses a special polymer material to open and reset the circuit automatically.
