Eaton 1.1 A Resettable Fuse, 6V

This resettable fuse provides reversible overcurrent protection for electronic systems, designed for low-voltage applications where repeated fault-clearing is required. It operates as a self-resetting polymer protection device that interrupts excessive current and returns to a conducting state once normal conditions resume, suitable for Compact surface-mount assemblies and reel-fed production lines.

• 50A current rating supports high transient currents while protecting circuits
• 1.1A hold characteristic prevents nuisance tripping during normal operation
• 1.8A trip current ensures fast response to moderate overloads
• 0.6W power dissipation limits thermal stress under continuous load
• 0.03-0.13Ω resistance range reduces voltage drop across the protection device
• -40°C to 85°C operating span maintains function across temperature extremes

• Suitable for automotive electronics requiring repeated reset after faults
• Ideal for power distribution modules in industrial automation
• Used with battery management systems in portable equipment
• Can be used for protection in control panels and sensing circuits
• Suitable for Compact consumer power supplies and chargers

Units are supplied on reels to facilitate pick-and-place mounting and efficient surface-mount production.

The device trips in approximately 0.3 s when the defined trip current is reached, providing prompt overload interruption.

The component is specified for use at up to 6 V, so system voltages should not exceed this value.

After the fault current falls below the hold level and temperature stabilises, it returns to a low-resistance conducting state without component replacement.
