PTC Resettable Fuses

PTC (Positive Temperature Coefficient) resettable fuses are electronic components used to protect against the overcurrent and overvoltage of electrical systems. A PTC resettable fuse is an electronic circuit protection device that is triggered when an overcurrent or overvoltage is detected. The device consists of a PTC thermistor, a temperature sensing element with a positive temperature coefficient of resistance, and an internal switching element.When an overcurrent passes through the fuse, the internal switching element is triggered, causing the PTC thermistor to increase its temperature and resistance. As the temperature of the PTC thermistor increases, the current through the fuse is reduced, effectively limiting the current and preventing further damage to the circuit. Once the overcurrent has been stopped, the internal switching element is reset and the PTC thermistor returns to its normal state.One of the most common type of PTC resettable fuses is the MF-R160-2, which is a “one-shot” type fuse. This type of fuse is designed to reset itself once the overcurrent has been stopped. It is rated for up to 160V AC or 89V DC and has a maximum interrupt rating of 10 A. The fuse has a fast response time, typically less than 10.0 ms, and it will normally trip within 0.20 ms when an overcurrent is detected.The MF-R160-2 is suitable for a wide range of applications, including telecom systems, power supplies, medical equipment, and consumer electronics. In addition, it can be used to protect automotive and industrial controls, HVAC systems, and lighting circuits. It can also be used in environments where a temperature-sensitive circuit needs to be protected from an overcurrent.The PTC resettable fuse is a reliable and economical way to protect circuits from overcurrent and overvoltage, both in industrial and consumer electronics. This type of fuse is designed to save time and money by eliminating the need to replace the fuse each time it has tripped and by allowing it to reset itself automatically after the overcurrent has been stopped. In addition, it provides excellent protection against short-circuits and can be used in a wide range of applications. Therefore, the MF-R160-2 is a great choice for any circuit protection needs.
