PTC resettable fuses are semiconductor devices designed to protect electronic circuits from over-current conditions. The PTC resettable fuse is also known as a polyfuse, polyswitch, polyrod, polyswitch fuse, or positive temperature coefficient fuse. These devices consist of a positive temperature coefficient (PTC) material that increases in electrical resistance with increasing temperature. When the current passing through the PTC fuse exceeds its rated value, it changes from a low resistance to a high resistance state. The device will remain in this high resistance state until the current is brought back below the rated value, at which point the PTC fuse returns to its low resistance state.

The 0ZCH0150FF2E PTC resettable fuse is a bi-stable, automatic reset device. It has a nominal working voltage of 1.50 to 2.50 Volts and a recommended operating temperature range of -25 to +125°C. It is designed for over-current protection in a variety of consumer electronics applications. These include portable medical equipment, wireless networks, small handheld devices, PC and cellphone power systems, and other mobile applications.

The working principle of the 0ZCH0150FF2E PTC resettable fuse is based on the behavior of a Positive Temperature Coefficient (PTC) thermistor. The material used in the construction of the PTC resettable fuse exhibits a resistance value that is proportional to the temperature at which the material is operating. When the device is exposed to a current above its rated value, the device heats up and the resistance of the material increases. This causes the current to reduce, which reduces the temperature of the material and the resistance begins to decrease again. As the temperature begins to return to its normal level, the current will start to rise again. The cycle will continue until the current is reduced to a safe level.

The 0ZCH0150FF2E PTC resettable fuse provides several benefits over other types of protection devices. It consumes almost no power when in its low resistance state, making it suitable for use in low power applications. It is also very reliable and does not require frequent replacement like other fuses, making it a cost-effective option. In addition, it has very low resistance values when in its low state, so it can be used to protect high current applications.

The 0ZCH0150FF2E PTC resettable fuse is a reliable solution for over-current protection in many consumer electronics applications. Its bi-stable design allows it to remain in its low resistance state, allowing it to protect components from over-current conditions in a cost-efficient and reliable manner. It is suitable for applications ranging from portable medical equipment to other small handheld devices.
