PTC Resettable Fuses, also known as positive temperature coefficient (PTC) resettable devices, are over-current protection components that offer the convenience of resetting simply by pressing a button while also providing reliable protection. 0ZSA0175FF1E is a series of PTC Resettable Fuses manufactured by Sanyo. This article will discuss the application field and working principle of 0ZSA0175FF1E.

Application Field of 0ZSA0175FF1E

0ZSA0175FF1E is a compact, power-saving resettable fuse with a low operating current and a low hold current. It is ideal for applications such as PC boards, power supplies, chargers, and battery management systems that require long-term, reliable over-current protection. It is also used in home automation systems, consumer electronics, and industrial equipment due to its wide operating temperature range and fast response time. Moreover, it is capable of protecting against both overcurrent and short circuit, making it suitable for a wide range of applications.

Working Principle of 0ZSA0175FF1E

0ZSA0175FF1E is a polymer PTC resettable fuse that can be reset with a simple manual push of a button. The working principle of this device is based on the principle of the Positive Temperature Coefficient (PTC). When an overcurrent or short-circuit condition occurs, the PTC thermistor will start to heat up due to the current running through it. As the PTC heats up, its resistance will increase which, in turn, will limit the current in the circuit. This will cause the temperature of the PTC to stabilize, and when it does so, it will act as an open circuit. To reset the device, the user simply has to press the reset button which will cause the PTC thermistor to cool down. As it cools down, its resistance will decrease, allowing current to run through the circuit again.

0ZSA0175FF1E PTC resettable fuses offer the convenience of resetting with just a button press while also offering reliable over-current protection. Its wide operating temperature range, fast response time, and ability to protect against both overcurrent and short circuit make it a great choice for a variety of applications.
