?The TECHFUSE SMD0805-050 with PTC Resettable Fuses 0805 RoHS is an integrated protection device designed specifically for space-constrained, low-voltage electronics boards. It combines a temperature-sensitive polymeric positive temperature coefficient (PTC) device with a miniature surface-mount fuse into a single packaged component. It is capable of providing high level protection to sensitive electronic components, such as memory, logic, and interface chips, from over-temperature and over-current conditions. The fuses are resettable after an over-current event and feature a low 0.05A current rating. It is manufactured using RoHS compliant materials and is designed to meet the requirements of the IEC 60950 safety standard. The compact 0805 package size of this SMD0805-050 with PTC Resettable Fuses allows for direct surface mounting, and the robust design enables protection in harsh environments.
