PTC Resettable Fuses
PTC Resettable Fuses, also known as Polymeric Positive Temperature Coefficient (PPTC) fuses, are type of resettable overcurrent protection devices used in electrical and electronic circuits instead of fuses or circuit breakers. PPTCs are inrush-current-controlled solid-state electrical devices that open during an overcurrent or short-circuit condition, and then restore to a closed state when the fault condition is corrected, allowing the original circuit to be used again. This capability of resetting can be done multiple times for an extended period of time without affecting the operation of the circuit. PPTC fuses offer overcurrent protection, reverse battery protection, over-temperature protection, and short-circuit protection, making them an ideal choice for applications requiring high levels of reliability. 16R250GU resettable fuses are widely used in various applications such as automotive, consumer, industrial, medical, and telecom devices. The active element of the 16R250GU devices is polymeric material that is specifically formulated with Electrical Characteristics (EC) and Polymeric Positive Temperature Coefficient (PPTC). This EC and PPTC provide the fuse with superior AC and DC protection characteristics. When the 16R250GU device is overloaded due to either DC or AC current, its resistance increases, causing the fuse to open and re-establish current flow through the circuit. Resetting the fuse is easy; it can be done manually or by using an automated reset circuit. When the fuse opens, it acts as an open circuit, breaking the current flow through the circuit and protecting the devices from any further damage.Another distinguishing feature of 16R250GU resettable fuses is its low current rating when operating at room temperature, 0.25A at 65 °C. This low rating ensures that any over-current condition does not cause the fuse to open immediately, resulting in a large current flowing through the circuit. This is also what allows it to be used for applications requiring higher reliable power distribution. In addition, 16R250GU resettable fuses have self-healing properties. This means that the fuse will autonomically re-establish the normal operation of the circuit if it detects any short circuit or over-current. It can repeat this self-healing process multiple times without affecting the performance of the fuse. The unique properties of the 16R250GU resettable fuses make them ideal for a number of applications. For example, they are used in computer motherboards, telecommunication systems, automotive control panels, and other high reliable power distribution systems. In addition, they can be used for controlling inrush current due to high capacitance in AC motors and switching power supplies. The 16R250GU resettable fuses are also used for protecting LED bulbs and strips from over-current and short circuits. In conclusion, the 16R250GU resettable fuses are a reliable and convenient solution for circuit protection in various applications. They can be used for controlling inrush current due to high capacitance in AC motors and switching power supplies, and for protecting LED bulbs and strips from over-current and short circuits. In addition, the resetting capability allows the original circuit to be used again and again for multiple cycles. Therefore, 16R250GU resettable fuses are ideal for applications requiring high levels of reliability.The specific data is subject to PDF, and the above content is for reference
