PTC Resettable Fuses

PTC resettable fuses, also known as positive temperature coefficient fuses, are a type of overcurrent protection devices that are employed to protect electronic systems from short-circuits and other overcurrents. The VTP170XSDDF type of PTC resettable fuses is a device designed for low-voltage consumer electronics applications, such as computers and mobile phones.

Application Field and Working Principle of VTP170XSDDF

VTP170XSDDF is an especially well-suited fuse for low-voltage consumer electronics applications, as it provides over-current and over-voltage protection, as well as fault isolation. The device has a fast response time and is self-resetting upon a fault.

The VTP170XSDDF works by utilizing a positive temperature coefficient (PTC) element which, when exposed to increased temperatures due to an over-current situation, increases the electrical resistance of the device. This opposes the current flow and causes the current to drop, thus effectively reducing the current.

The device is triggered by an over-current situation and this triggers the self-resetting mechanism which switches off the current and isolates the fault. After some time, the device resets itself and the current flow can be reinstated.

The VTP170XSDDF is a great versatile device, designed to respond to over-current situations quickly and reliably with very little impact on the protected circuit. It is simple to install, reliable in operation and affordable. The device is also available in both standard and custom configurations, so it can be adapted to specific application requirements and offer customized solutions.

In addition, the VTP170XSDDF is also RoHS compliant and UL-certified, making it excellent for applications in the consumer electronics industry. The device is also extremely small in size, allowing for easy integration and minimal memory usage.
