The SPXI015.L is a PPTC (Polymeric Positive Temperature Coefficient) resettable fuse manufactured by Littelfuse. This device protects electronic circuits from overcurrent conditions by increasing its resistance dramatically when a fault occurs, limiting the current flow. Once the fault is removed, the device cools down and returns to its low-resistance state, allowing the circuit to resume normal operation.

Applications

• USB ports
• Computer peripherals
• Mobile phones
• Game consoles
• General electronics protection

Features

• Resettable overcurrent protection
• Compact size
• Low resistance
• Fast trip time
• RoHS compliant
• Agency approvals (UL, CSA, TUV)

Benefits

• Protection against overcurrent faults
• Elimination of fuse replacement
• Reduced warranty costs
• Improved product reliability
• Automatic reset after fault removal
• Safer operation

Additional Details

The SPXI015.L is designed to protect electronic circuits from damage caused by overcurrent conditions. When the current exceeds the rated trip current, the PPTC device heats up and its resistance increases significantly, limiting the current flow and protecting the circuit. Once the overcurrent condition is removed, the device cools down and its resistance returns to its normal low-resistance state, allowing the circuit to resume normal operation. This resettable functionality eliminates the need to replace fuses, reducing maintenance costs and improving product reliability.

The SPXI015.L is commonly used in USB ports to protect against short circuits and overloads. It is also used in computer peripherals, mobile phones, and game consoles to protect sensitive electronic components. Its compact size makes it suitable for use in space-constrained applications. The device meets RoHS compliance standards, ensuring that it is environmentally friendly. It also has agency approvals from UL, CSA, and TUV, indicating that it meets safety standards. The SPXI015.L provides reliable overcurrent protection and helps to prevent damage to electronic circuits, ensuring safe and reliable operation of electronic devices.
