PTC Resettable Fuses

PTC Resettable Fuses are used for protection of circuits that require large current and short circuit protection, such as power supplies and motor controllers. They provide a reliable and cost effective solution to the problem of over-current and short circuit in a system.A PTC (positive temperature coefficient) resettable fuse is an electro-thermal device that is used to protect circuits from over-current and short circuit conditions. The device works by increasing its resistance with respect to increasing current, and thus limits the current through the circuit. When the current is too high, the device heats up and the resistance increases thus limiting the current further. This “thermal runaway” phenomenon limits the current to a safe level and protects the circuit from damage. When the current decreases, the PTC resettable fuse will cool and reset itself, thus allowing the circuit to resume normal operation.In application 0ZCJ0035AF2E, a PTC resettable fuse is used to detect and limit over-current and short circuit conditions. The device works by increasing its resistance with respect to increasing current, and thus limits the current through the circuit. The device is also designed to reset itself once the current is brought back below the limit. This allows the circuit to resume normal operation, without requiring manual intervention.The advantages of using a PTC resettable fuse over other types of protection devices include:* Improved safety: The device is designed to protect circuits from catastrophic damage through an “unlimited” current limit.* Increased reliability: The device will reset itself when conditions return to normal, allowing the circuit to resume normal operation without the need for manual intervention.* Reduced design complexity: By incorporating a single resettable device instead of multiple devices with different ratings, the overall circuit complexity is reduced* Cost savings: The device is a one-time investment with no additional components required for operation.The 0ZCJ0035AF2E PTC resettable fuse has been designed to be used in an AC circuit of up to 250 volts, with a short circuit capacity of 1500 Amps. The device is capable of operating at temperatures up to 125°C and is RoHS compliant. It also features an over-current protection point at 500 mA.In summary, the 0ZCJ0035AF2E PTC resettable fuse provides a reliable and cost effective solution to the problem of over-current and short circuit conditions in a system. It is designed to detect over-currents and limit them safely while resetting automatically when conditions return to normal. The device is capable of being used in an AC circuit of up to 250 volts, with an over-current protection point of 500 mA.
