PTC Resettable Fuses are a type of fuse that can be manually reset after being triggered by an external factor. By using a low-value thermal resistor, the fuses can detect an overcurrent or overvoltage event, and cutoff the circuit to protect the components. 1206L500SLWR is a PTC Resettable Fuses designed with ultra-low resistance of 0.1 ohm, ultra-low voltage drop, and ultra-high current up to 120A.

The 1206L500SLWR fuse has a wide variety of applications, from consumer electronics to automotive applications. It is often used to protect sensitive components from overcurrent and overvoltage, or to protect circuits from short circuits or power surges. In addition, it can be used as part of a fuse resistor, allowing the user to select the precise current level needed for their application.

The working principle of a 1206L500SLWR PTC Resettable Fuse is based on the thermal resistors used in its design. When current flows through the fuse, it will generate heat and cause the thermal resistor to increase in resistance. The resistance of this component is temperature-dependent, so as the temperature increases or decreases, the resistance will change accordingly. When too much current is flowing through the fuse, the thermal resistor will increase its resistance, causing the fuse to trip and cut off the power flow. In order for the fuse to be reset, the temperature must be reduced to a normal level.

The 1206L500SLWR PTC Resettable Fuse is designed with an extremely low voltage drop of 0.2V and a maximum current rating of 120A. It is also designed with a thermal resistor that can accurately detect current levels up to 6 times its rating. This makes it ideal for applications requiring precise current detection and protection from high current surges. In addition, this thermal resistor is self-healing, meaning that the fuse can be reset after a triggering event without having to be replaced.

The 1206L500SLWR PTC Resettable Fuse is a reliable way to protect sensitive components and circuits from overcurrent and overvoltage events. It can accurately detect overcurrent levels and safely trip the circuit to protect the device, yet can be easily reset once the temperature is reduced. With its extremely low resistance, voltage drop, and high current rating, this fuse makes an ideal choice for a wide range of applications.
