PTC Resettable Fuses are designed to protect electronic circuits from over-current and short-circuit. The 0ZCF0125FF2C is a resettable fuse, or Polymeric Positive Temperature Coefficient (PPTC) Resettable Fuses, which controls and limits inrush current surge on power up.

Application Field

0ZCF0125FF2C\'s could be widely used in the fields such as power supply, charger, industrial equipments, automotive electronic gadgets, medical automation, home automated equipment, battery power products and so on. Besides, what makes 0ZCF0125FF2C different from normal PTC resettable fuses is that it has compact size, low operating temperature, high tripping current, and low cost. Therefore, 0ZCF0125FF2C is also a good choice for applications where space and cost are both important factors.

Working Principle

The working mechanism of the 0ZCF0125FF2C is relatively simple. It is composed of two elements: a temperature sensing component and current sensing component. First, the current sensing component senses the current that passes through the fuse. Then, depending on the current, the temperature sensing component heats up and drastically increase its resistance. When this resistance reaches a predetermined level, the temperature sensing component shuts off the flow of current. This shut-off eventually causes the device to cool down and the resistance to reduce.

The 0ZCF0125FF2C has a feature called automatic reset. When the preset current is exceeded and the device is shut off, once the device cools down the device will automatically reset and return to its normal state. This automatic reset feature allows the device to be used multiple times without any interference between the user and the device, making it ideal for applications that require frequent resetting and have a large external heat sink. Furthermore, the 0ZCF0125FF2C has a low hold current which ensures that the device will not operate, while the current is low.

In conclusion, 0ZCF0125FF2C is a reliable and easy to use resettable fuse that is perfect for applications that require frequent resetting and have a large external heat sink. Its low cost, compact size, low operating temperature and high tripping current make it an ideal choice for a variety of applications.
