PTC resettable fuses provide a simple and cost-effective solution for over current protection. 0ZCJ0075FF2E is one of the commonly used multi-function PTC products for over current protection. The application field and working principle of 0ZCJ0075FF2E will be discussed in this article.

In general, 0ZCJ0075FF2E are designed for electronic protection applications in laptops, set-top boxes, tablet devices, home appliances and game consoles. Additionally, considering their superior performance in terms of over current protection, they can also be deployed in a variety of power and control applications such as fan controls, motor drives, relay controls and motor speed controllers. With their excellent heat resistance and fast reset properties, they are suitable for applications in extreme temperature ranges.

When it comes to operation, 0ZCJ0075FF2E works based on the thermistor-resistor (TR) principle. The product has an embedded thermistor device that acts as the temperature sensing element. When the current passes through it, the thermistor device will heat up and create a temperature difference between the two terminals. In this manner, the thermal protection is activated and the current is prevented from flowing further, thereby protecting the device from overheating.

In addition, 0ZCJ0075FF2E boast up to 1,000 A/W of current limiting capability, meaning they are capable of limiting the current in case of any abnormal short circuit. As a result, they provide the necessary protection against fire and damages to sensitive components in the event of an over-voltage or over-pressure situation. Furthermore, the 0ZCJ0075FF2E are capable of resetting in a matter of seconds, thereby ensuring fast and effective over-current protection.

Finally, the 0ZCJ0075FF2E come equipped with a built-in reset circuit, which enables them to reset automatically after the fault has been cleared and the current level returned to normal. Additionally, they can be programmed with customized settings and user-defined trip points to provide additional flexibility for different application requirements.

In sum, 0ZCJ0075FF2E is an ideal solution for over-current protection and related applications. It is capable of withstanding extreme temperatures and has a high current-limiting capability, making it suitable for use in a variety of environments. Furthermore, it features a built-in reset circuit, allowing it to reset in a matter of seconds after the fault has been cleared. As such, 0ZCJ0075FF2E is a cost-effective and reliable solution for electronic protection.
