PTC Resettable Fuses are commonly used as over-current and over-temperature protection devices. These types of fuses operate by using a Positive Temperature Coefficient (PTC) element that reacts to heat generated by high current. The YS5921PTO is one such device.
The YS5921PTO provides protection against over-current. It works by detecting currents higher than the initial set current and then resetting after the current is reduced. This resetting action is achieved by the high thermal conductivity of the PTC element. The PTC element detects heat generated by the high current, which causes it to expand, thus increasing its resistance. This increase in resistance reduces or stops the current momentarily, resulting in the fuse resettting.
The YS5921PTO is used in a wide range of applications. These include protection of automotive lighting and accessory circuits, appliances, power supplies, home entertainment systems, sound systems, computers, and even medical equipment. The fuse is also suitable for protecting circuits from short-circuits, over-voltage, over-charging and over-discharging.
The YS5921PTO has a wide working temperature range from -55°C to 125°C, making it suitable for use in a large number of environments. The maximum rated current and voltage are 25A and 32V, respectively. The fuse has a low profile design which makes it easy to install and has a small size for space-constrained applications.
The YS5921PTO is available in a variety of packages including surface mount, radial leaded, and axial leaded. All packages use a lead-free design that are RoHS compliant. The PTC element is encapsulated in a UL94V-0 rated ABS plastic body.
In summary, the YS5921PTO is a PTC Resettable Fuse that provides over-current protection for a wide range of applications. It is available in a variety of packages and has a wide operating temperature range. It also uses a UL94V-0 rated ABS plastic body and is RoHS compliant. The low profile design makes it easy to install and fits in compact spaces.
