PTC (positive temperature coefficient) resettable fuses, also often known as polyfuses, are a type of electrical components used to protect sensitive electronics against faults caused by excessive current. The 0ZCM0020FF2G, a new generation PTC resettable fuse designed by Zener Components, Inc., is ideal for applications that require medium and high current protection. This article will explore the application field and working principle of the 0ZCM0020FF2G.

Application Field of the 0ZCM0020FF2G

The 0ZCM0020FF2G is suitable for a variety of applications that require medium and high current protection, such as Computers, cell phones, tablets, routers, servers, uninterruptible power systems (UPS), CCTV cameras, automotive electronics, LCDs, printers, digital media players, security systems and many other devices. In addition, it can also be used as a replacement for slotted disc fuses, which are often used to protect printed circuit boards from damage caused by circuit overloads.

The 0ZCM0020FF2G can be used to protect devices from voltage spikes and short circuits, and it can detect the presence of a current flow as low as 2 milliamps (μA). With a continuous current rating of 20 amps and an overload rating of 35 amps, it is ideal for applications that require medium and high current protection.

Working Principle of the 0ZCM0020FF2G

The 0ZCM0020FF2G works by using a PTC (positive temperature coefficient) thermistor element, which is designed to limit the amount of current that flows through it. When the current exceeds the rated value, the PTC thermistor element will begin to heat up. This increases its resistance, thus limiting the amount of current that can flow through it and preventing a short circuit from occurring. The current remains limited until the PTC element cools down and the fuse is reset.

The 0ZCM0020FF2G is also designed with a built-in indicator that visually indicates when the fuse is activated. This allows users to quickly and easily determine the status of the fuse, which is useful in situations where the amount of current is critical. The 0ZCM0020FF2G is designed with a rugged case that is resistant to shock, vibration, and corrosion, making it an ideal choice for harsh environments.

Conclusion

The 0ZCM0020FF2G PTC resettable fuse is a versatile and reliable device that is suitable for a wide range of applications that require medium and high current protection. It is designed with a built-in indicator that indicates when the fuse is activated, which allows users to quickly and easily determine the status of the fuse. The 0ZCM0020FF2G is designed with a rugged case that is resistant to shock, vibration, and corrosion, making it an ideal choice for harsh environments.
