RGEF300-2

PTC (Positive Temperature Coefficient) Resettable Fuses are electrical components designed to provide a current limiting capability (overcurrent protection) in a wide variety of applications. These devices are capable of allowing normal currents to flow until the current level crosses a predetermined threshold value, at which point a fast, irreversible reaction occurs. RGEF300-2 is one of the specific varieties of PTC resettable fuses, and it is suitable for the power supply and the stored current application environment.

Overview of RGEF300-2

RGEF300-2 is a PTC fuse that is designed to protect sensitive electronic components from overcurrent conditions. It offers excellent high current and short circuit protection, and can help to ensure the safety and reliability of a wide range of devices. The maximum working current of RGEF300-2 is 300A, with a hold current of 90A and surge current of 300A. It also boasts a response time of 10ms, which ensures that it can adequately protect against high currents. Additionally, the life expectancy of the RGEF300-2 is greater than 1000 cycles, which further ensures that it will last for a long time.

Application Field of RGEF300-2

The RGEF300-2 is designed for use in a variety of applications. This device is especially suitable for applications where the device will be subject to high levels of current flow, such as power supplies, UPS systems, LED drivers, and circuit boards. The RGEF300-2 can also be used in automotive and industrial applications, as it is capable of withstanding temperatures ranging from -40°C to +85°C.

Working Principle of RGEF300-2

The working principle of the RGEF300-2 is based around its PTC-based design. When the current level exceeds the predetermined threshold, a metallic-based heater element begins to heat up rapidly. This causes a rapid expansion of the PTC element, which acts as a fuse and causes a power interruption. When the power is interrupted, the heater element cools down, and the PTC element contracts back to its original size. This enables the device to reset and resume regular current flow.

Advantages of RGEF300-2

The RGEF300-2 offers a number of advantages that make it an ideal choice for a wide variety of applications. It is capable of providing excellent protection against current over-load and short circuit conditions, as its response time of 10ms is very fast. Additionally, this device is able to reset itself after an over-current condition has occurred, which eliminates the need for manual resetting. It is also able to withstand a wide temperature range, making it suitable for both commercial and industrial applications.

Conclusion

The RGEF300-2 is an excellent choice for many applications that require current limiting protection. It offers high current and short circuit protection, as well as a fast response time and a high life expectancy. Furthermore, its ability to reset automatically makes it convenient and reliable. All of these qualities make the RGEF300-2 an ideal choice for power supply, UPS systems, LED drivers and circuit boards.
