The 1812 surface-mount PTC resettable sensor features a full-faced termination design. The Overcurrent Circuit Protection Guide provides a tutorial on the design characteristics and different technologies of both a Positive Temperature Coefficient (PTC) resettable device and fuse. The guide provides a glossary of PTC terms and includes typical PTC ratings for voltage, current, temperature, and other parameters. Applications such as computers and peripherals for PTC resettables are also included.
