PTC Resettable Fuses

PTC resettable fuses or polymeric positive temperature coefficient (PPTC) devices are current-limiting devices that can be used to protect against circuit overloads and short circuits. The 0ZRE0200FF1A is a PTC resettable fuse that is designed to protect circuits from overcurrent. In this article, we will discuss the application field and working principle of the 0ZRE0200FF1A.

Application Field

The 0ZRE0200FF1A is designed to provide current limiting and circuit protection in such applications as DC power supplies, computing systems, telecommunications equipment, consumer electronics, and industrial equipment. This device is available in a variety of package styles to accommodate a wide range of application requirements.

In addition to its current-limiting and circuit-protection properties, the 0ZRE0200FF1A is designed to provide high reliability and long life. It is able to withstand temperatures up to 250°C and has a maximum current rating of 3.5A. It is also designed to be flexible and to be able to fit into a variety of component packages.

Working Principle

The 0ZRE0200FF1A operates on the principle of a polymeric positive temperature coefficient (PPTC). When a current greater than the device\'s rated value flows through it, the PPTC will begin to increase in resistance. This increase in resistance will result in a rapid decrease in the current flowing through the device, limiting the current to a value that is safe for the circuit.

The PPTC will remain in its increased resistance state until the current is reduced to a safe level. After the current is reduced, the PPTC will return to its normal resistance level and the device will be ready to be used again. In this way, the 0ZRE0200FF1A can be used to protect circuits from overcurrent.

Conclusion

The 0ZRE0200FF1A is an example of a PTC resettable fuse that can be used to provide current limiting and circuit protection. It is designed for use in a variety of applications, such as DC power supplies, computing systems, telecommunications equipment, consumer electronics, and industrial equipment. It operates on the principle of a PPTC and is able to withstand temperatures up to 250°C and has a maximum current rating of 3.5A.

In conclusion, the 0ZRE0200FF1A is a versatile and reliable device that can be used to protect circuits from overcurrent. It is available in a variety of package styles and is designed for high reliability and long life.
