Introduction to PTC Resettable Fuses

PTC resettable fuses are a type of circuit protection device used to protect circuits from overvoltage, overcurrent, and overtemperature. PTC stands for Positive Temperature Coefficient, and these components are also referred to as polymeric positive temperature coefficient (PPTC) devices. Unlike traditional fuses, PTC resettable fuses will trip at a certain level of current or temperature, and then can be reset with the application of an external voltage. This makes them ideal for protecting against frequent power outages or surges.

0ZCC0020FF2C Application Field and Working Principle

The 0ZCC0020FF2C is a polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by Zettler Components. It is designed for use in a wide range of applications including over-current protection in consumer electronics, telecom, energy storage equipment, LED lighting, automotive systems and power supplies.This PTC resettable fuse features a wide operating temperature range from -40°C to 85°C and a wide resistance range from 0.6 ohm to 10.5 kohm. The maximum operating voltage is 16V.The 0ZCC0020FF2C works on the principle of thermal runaway. When current passes through the PTC device, heat is generated. This heat increases the resistance of the device, and eventually trips the fuse when the current is above the set threshold level. Once the current is reduced, the PTC resettable fuse will cool and reset itself.

Conclusion

The 0ZCC0020FF2C is a polymeric positive temperature coefficient (PPTC) resettable fuse that is suitable for a wide range of applications. It can be used to protect against overcurrent, overvoltage, and overtemperature, and it features a wide operating temperature range from -40°C to 85°C and a wide resistance range from 0.6 ohm to 10.5 kohm. This PTC resettable fuse works on the principle of thermal runaway, tripping at a certain level of current and resetting with a reduction of current.
