The miniSMDC150F/12 is a PolySwitch resettable fuse from TE Connectivity (formerly Tyco Electronics). It's a surface mount device (SMD) designed to protect electronic circuits from overcurrent conditions. These devices enhance the reliability of electronic equipment by preventing damage caused by temporary overcurrent faults. It is characterized by its small form factor and its ability to reset after the fault condition is removed, making it suitable for applications where continuous operation is crucial.

Applications

• USB port protection: Protects USB ports in computers, laptops, and peripherals.
• Mobile phone charging circuits: Safeguards charging circuits in mobile phones and tablets.
• Game consoles: Provides overcurrent protection for gaming consoles.
• General electronics: Can be used in various electronic devices requiring overcurrent protection.
• Point of Sale (POS) Equipment Protection for sensitive POS electronics.

Features

• Resettable: Automatically resets after the overcurrent condition is removed, eliminating the need for manual replacement.
• Surface Mount Device (SMD): Easy to integrate into automated assembly processes.
• Compact Size: Small footprint allows for use in space-constrained applications.
• Fast Trip Time: Quickly interrupts the current flow during an overcurrent event.
• Low Resistance: Minimizes power loss during normal operation.
• Agency Recognition: UL, CSA, and TUV approvals.

Benefits
