The 2016L100PR is a surface-mount resettable fuse (PPTC) manufactured by Littelfuse Inc. PPTC stands for Polymeric Positive Temperature Coefficient. These devices are used for overcurrent protection in electronic circuits. Unlike traditional fuses that blow and need replacement, PPTC fuses automatically reset themselves once the overcurrent condition is removed, making them ideal for applications where serviceability is important.

Applications

• USB port protection
• Rechargeable battery packs
• Game consoles
• Portable electronics
• General overcurrent protection

Features

• Resettable overcurrent protection
• Surface mount package
• Fast trip time
• Low resistance
• Compact size

Benefits

• Reduced downtime due to automatic reset
• Lower maintenance costs
• Improved system reliability
• Protection against overcurrent and short circuits
• Simplified circuit design

The 2016L100PR is designed to trip quickly when an overcurrent condition occurs, limiting the current flow and protecting the circuit. Once the fault is cleared and the power is removed, the PPTC fuse cools down and its resistance returns to a low value, allowing normal operation to resume. The surface-mount package makes it easy to integrate into modern electronic devices.

Resettable fuses like the 2016L100PR provide a convenient and reliable solution for overcurrent protection. They are commonly used in portable devices to protect against short circuits and overloads. Refer to the official datasheet for detailed electrical characteristics, trip current specifications, and recommended operating conditions to ensure proper selection and application of the device.
