PTC Resettable Fuses are designed for overcurrent protection of electronic circuits, and VTP175F is their most reliable and efficient product. With its unique architecture, VTP175F has become the industry leader for overcurrent protection, and its easy-to-use technology has made it the standard for home and industrial applications.

VTP175F is a polymer positive-temperature-coefficient (PPTC) resettable fuse designed for overcurrent protection. It is a miniaturized version of a conventional fuse that remains in the circuit and does not need to be replaced after tripping. The VTP175F is composed of two electrodes attached to a polymer film that contains carbon particles, which are embedded in a conductive matrix. It has a rated current of 4.0A and holds up to 175V.

VTP175F is widely used in industrial, power, telecom, medical, military, automotive, consumer devices, and remote, solid-state drive, LED lighting, energy-saving, and solar photovoltaic fields. The VTP175F\'s simple design and reliable performance make it ideal for these applications. It prevents short circuits, fire, and other costly damage in home appliances, solar components, cellular phones, and many more.

The working principle of the VTP175F is pretty simple. When the current exceeds its rated value, VTP175F will start to heat up and get deformed due to the Joule heating effect. This expansion in the film causes a resistance in the current path. The resistance increases exponentially with increasing temperature, leading to a controlled current-limiting operation. With this action, the power supply and the device connected to it are protected from the overvoltage, leading to lesser damage or short circuits. After the current flows through the fuse, the temperature decreases, and the device returns to its original shape. This repetitive process of heating and cooling results in a resettable fuse.

In summary, the VTP175F is an important product in the field of PTC Resettable Fuses, and their capabilities provide the user with a reliable and easy-to-use solution for overcurrent protection in many different applications. The simple design and reliable performance make them ideal for uses in home and industrial applications, and they have proven to be a great way to prevent costly damage in electronic circuits.
