PTC Resettable Fuses PTC (Positive Temperature Coefficient) Resettable Fuses are a type of current-limiting device that are used to provide overcurrent protection for sensitive electronics and other electrical systems. The main advantage of these fuses is that they can be reset and reused multiple times, unlike standard fuses which must be replaced after each incident. As such, they are particularly well-suited for applications where intermittent overcurrents may occur, such as in automotive systems and other critical circuits.The 1206L016WR is a typical PTC Resettable Fuse, and is commonly used in a range of consumer electronics and other applications to provide overcurrent protection. This device is offered in a 1206 surface mount package, and offers a rated current of 16A (Amp) and a rated voltage of 32V (Volts). The 1206L016WR also has a resistance of 0.4 Ohms (at 20°C) and a temperature rating of -40℃ to +85℃.PTC Resettable Fuses have two main working principles that work together to limit the amount of current flowing through a circuit. The first is a temperature-sensitive mechanism, where an increased current creates more heat and causes the fuse to open the circuit by melting the PTC element. This creates a sudden break in the power flow, thereby limiting any current spikes. The other mechanism is a mechanical trip breaker, which can open up the circuit due to the physical movement of the internal parts. This further provides overcurrent protection, especially in the event of continuous current overloads.The 1206L016WR fuse is designed to be fast-acting and responds within 100ms at a 10x overload current. It also features a low trip level of 1.6x the rated current, making it a reliable overcurrent protection device. It also has a low temperature coefficient, making it well-suited for applications with varying ambient temperatures.When it comes to applications, PTC Resettable Fuses can be used in automotive systems, including USB-C charging ports, electric showers and air conditioning controllers. They are also used in consumer appliances, such as washing machines, dryers and electric kettles, as well as in industrial applications including wind turbines, medical imaging systems and inverters. They are also used in aerospace systems, particularly in circuits where high switching frequencies are employed.The 1206L016WR fuse is designed to meet the requirements of modern industrial and home automation equipment. The device is RoHS-compliant and has an excellent long-term stability, making it suitable for use in harsh environments. It also has a high resistance to shock and vibration, making it an ideal choice for rugged applications.Overall, the 1206L016WR PTC Resettable Fuse is a reliable and cost-effective current-limiting device well suited for a wide range of applications. With its fast-acting response, low trip level thermostat and temperature coefficient, the 1206L016WR is an ideal choice for overcurrent protection.
