The RF1347-000 is a resettable fuse, specifically a PolySwitch device manufactured by Littelfuse Inc. It is designed to protect electronic circuits from overcurrent and overtemperature conditions. These fuses are self-resetting, meaning they return to their conductive state after the fault is removed, eliminating the need for manual replacement.

Applications:

• USB ports: Providing overcurrent protection for USB ports in computers, peripherals, and chargers.
• Power supplies: Protecting power supplies from overloads and short circuits.
• Battery packs: Protecting lithium-ion and other battery packs from overcurrent and overtemperature conditions.
• Automotive electronics: Protecting various automotive electronic systems from faults.
• Industrial control systems: Protecting industrial control equipment from overcurrent and overtemperature damage.

Features:

• Resettable fuse: Automatically resets after the overcurrent or overtemperature fault is cleared.
• Surface mount device (SMD): Facilitates automated assembly processes.
• Compact size: Allows for high-density mounting on printed circuit boards.
• Low resistance: Minimizes voltage drop during normal operation.
• Fast trip time: Quickly responds to overcurrent and overtemperature conditions.

Benefits:

• Improved circuit protection: Provides reliable protection against overcurrent and overtemperature faults.
• Reduced downtime: Eliminates the need for manual fuse replacement.
• Compact design: Suitable for applications with limited board space.
• Enhanced safety: Protects electronic devices and users from potential hazards.
• Cost-effective solution: Offers a balance of performance and value for circuit protection.
