About PTC Resettable Fuses


Positive Temperature Coefficient (PTC) resettable fuses are innovative components in the electronics industry that automatically reset after a fault condition is cleared. These fuses exhibit a resistance that increases with temperature, causing a self-limiting effect during overcurrent situations. PTC resettable fuses are widely used in applications where protection against overcurrent events is essential, such as in power supplies, batteries, and automotive electronics. Their ability to reset and restore functionality makes them a convenient and reliable choice for continuous protection.
