Polymeric Resettable Fuse PTC - 6V, 500mA
This is a handy little device that can save your system from smoking. A resettable fuse is a resistor that has very unique properties.
For this model, if your circuit tries to draw more than 500mA of current (if you have a bad short for instance) the PTC would 'trip' (by heating up). The increased resistance (trip state) would break the circuit and allow only a small leakage current.

DatasheetProduct Overview
This is a handy little device that can save your system from smoking. A resettable fuse (also known as a PTC) is a resistor that has very unique properties.
For this model, if your circuit tries to draw more than 500mA of current (if you have a bad short for instance) the PTC would 'trip' (by heating up). The increased resistance (trip state) would break the circuit and allow only a small leakage current.
The leakage current may still be enough to hurt some electronics but it's much less than the 1A that the short may have allowed. Removing the short, the PTC 'resets' and allows current up to 500mA to flow again. It's a resettable fuse that protects your system! Good for use on battery powered devices that need to protect again high-current accidental discharges.
