The Littelfuse 1210L010WR is a 1210 size surface mount resettable PTC (Positive Temperature Coefficient) fuse. These devices are used to protect circuits from overcurrent conditions. They offer a reliable and predictable method of circuit protection, automatically resetting after the fault condition is removed and power is cycled.

Applications

• USB port protection: Protecting USB ports in computers, peripherals, and other devices.
• HDMI port protection: Preventing damage to HDMI ports from overcurrent events.
• Power supply protection: Limiting current in power supplies to prevent component failure.
• Game consoles: Overcurrent protection in gaming devices.
• General electronic equipment: Used broadly in electronic devices to protect sensitive components.
• Mobile phones and tablets: Overcurrent protection for internal circuits.

Features

• Resettable: Automatically resets after the overcurrent condition is removed.
• Surface mount: Designed for surface mount PCB assembly.
• Compact size: 1210 footprint for space-constrained applications.
• Fast trip time: Quickly reacts to overcurrent events.
• Low resistance: Minimizes voltage drop during normal operation.
• Agency approvals: UL, CSA, and TUV approvals for safety and reliability.

Benefits

• Circuit protection: Prevents damage to sensitive components from overcurrent conditions.
• Reduced downtime: Eliminates the need to replace blown fuses, reducing downtime and maintenance costs.
• Improved product reliability: Enhances the reliability of electronic devices by protecting them from overcurrent events.
• Cost-effective: Offers a cost-effective solution for circuit protection compared to traditional fuses.
• Space-saving: Compact size allows for use in space-constrained applications.
