B59206R0135B010

PTC Resettable Fuses, such as B59206R0135B010, are designed to protect electronics against short circuit, reversed power supply and low-voltage connection in harsh environments. This is made possible by their fail-safe design, which combines traditional fuse or current-limiting circuits with a special polymeric Positive Temperature Coefficient resistors. By doing so, PTC resettable fuses can not only open a circuit automatically when the current exceeds the maximum set current, but also reset after the current drops back to normal levels.

The application of B59206R0135B010 can be found on almost all consumer products and in a wide variety of industries, such as automotive, medical equipment, industrial equipment, power supply, aerospace and military. Other applications include communications, computers, home appliances and consumer electronics.

The working principle of B59206R0135B010 is simple. It uses two elements to determine the level of current: an PTC (Positive Temperature Coefficient) resistor and a fuse. The PTC\'s resistance increases exponentially when its own temperature rises. The fuse element is a small piece of metal which melts when excessive current flows through it. When the current reaches a certain level, the PTC\'s resistance increases and causes the current to drop, while the fuse element melts and opens the circuit, shutting off the current.

Once the current drops below the maximum set current, the fuse element cools and reforms, allowing the current to flow through the circuit again, while the PTC\'s resistance decreases. This is how B59206R0135B010 acts as a resettable fuse, resetting automatically after the current drops below the set level. This unique combination of components enables the fuse to provide an extremely low resistance path for normal levels of current, while also providing a high-resistance path for overload conditions.

B59206R0135B010 is a significant advancement in the protection of electronics. It is capable of resetting itself after each surge, providing greater reliability and improved safety. This resettable fuse offers unlimited protection cycles, meaning it does not need to be replaced after each surge. This makes it extremely cost effective, as compared to traditional fuses, where each surge requires a new fuse. Furthermore, its small size, light weight and wide operating temperature range make it an ideal choice for compact, high-performance applications.

By combining the two components - the PTC and the fuse - in one unit, the B59206R0135B010 fuse provides the highest level of protection against short circuits, reversed power supplies and low-voltage connections. Its ability to provide unlimited protection cycles and its cost-effectiveness make it the ideal solution for a wide range of applications.
