PTC Resettable Fuses are commonly used devices in various applications. These devices are created using a conductive polymer pressurized between metal plates with an integrated thermal switch mechanism. This mechanism will cause a temporary disconnect in current once a certain temperature is reached. The B59773B0120A070 is a device that falls under this category. This article will focus on its application field and working principle.

The B59773B0120A070 is suitable for use in many different power control and electronic systems, such as soft starters, inverters, power supplies, motor control systems, transformers and more. It is also specifically designed to be used to of an overcurrent situation on portable medical devices, such as ventilators and respirators. Apart from these specific applications, it can be used to provide an extra level of protection in any circuit where it is important to ensure a stable current is maintained at all times. In addition, the device is designed with a wide range of tolerances, making it suitable for use in both low and high power applications.

The working principle of the B59773B0120A070 is quite simple. The device includes two small metal plates which are separated by a conductive polymer. This is pressurized between the two plates to ensure a consistent connection. When a certain temperature is passed, usually due to an over current situation, the conductive polymer will no longer be able to maintain a complete connection between the two plates. This causes a temporary break in the current passing through the circuit. As soon as the temperature is reduced the conductive polymer will return to its pressurized state once again, thus allowing current to pass through the circuit.

In conclusion, the B59773B0120A070 is a device specifically designed for use in a range of different electronic circuits in order to offer additional protection for sensitive components. It works by using a conductive polymer that is pressurized between two metal plates. Once the temperature is exceeded, the connection between the two plates is broken, resulting in a temporary break in the circuit.This process can then be repeated until the over current situation is eliminated. The wide range of tolerances and versatile application fields of the device make it suitable for use in almost any type of system, from portable medical devices to high power electronics.
