PTC Resettable Fuses are advanced technology over-current protection components. These are also referred as Polyswitch, polyfuse, or Melamine Fuses. The main distinguishing feature is the way the overcurrent fault is cleared. A PTC Resettable Fuse rapidly self-resets and restores its conductive state after overcurrent fault condition is removed. 0ZRC0110FF2B is PTC resettable fuse.

Application Field:

0ZRC0110FF2B PTC Resettable Fuse is used for various applications and it can provide low impedance short circuit protection for a wide range of over-current conditions. With the accurate trip current and fast response time, the 0ZRC0110FF2B is a popular choice for telecom systems, household appliances, consumer electronics, medical equipment, industrial electronics, and automotive applications. The common application is to protect DC motors, LEDs, power switching circuits or batteries backup circuit for cell phone and laptop devices.

Working Principle:

The 0ZRC0110FF2B is a current limiting PTC resettable fuse that integrates PTC and fuse technology to provide two levels of over-current protection. At the first level, the 0ZRC0110FF2B PTC Resettable Fuse acts as an ordinary fuse. When the current exceeds the fuse\'s threshold value, the metal wire within the fuse heats up and melts, breaking the circuit and stopping the current flow. Since the component’s current rating and trip time vary slightly between devices, the 0ZRC0110FF2B incorporates precise engineering techniques to provide reliable and consistent over-current protection.At the second level, when the threshold is reached, the PTC element activates and can regulate the current flow. The PTC element acts as a temperature-dependent resistor that keeps the current levels in check until the temperature of the element rises enough to shift the entire device into a high-impedance state. In this state, the current flow quickly drops off and the 0ZRC0110FF2B becomes an open circuit, providing over-current and short-circuit protection. The PTC element then cools down and shifts back to its low impedance state, thus restarting the current flow.

To sum up, 0ZRC0110FF2B PTC Resettable Fuse is a two-level over-current protection device that can provide an effective solution for withstanding a wide range of short circuit and over-current conditions. It integrates the advantages of both the fuse and PTC technology and is highly reliable and suitable for various electronics application.
